If you have to jump into the deep end without getting your feet wet first by seeing reviewed providers. Here a recommended process. Lets say you want to see a girl who does not have any reviews and is posting on say for instance Backpage. There is an extremely high risk of getting
ripped off or having a bad time. Yet here is very rough draft of how I recommend proceding.

1- Don't answer an ad where the pictures look too good to be true. They usually are.
  Most model type beautiful women don't post on Backpage type websites. The pics are fake.
2- As a Newbie don't answer an ad for a provider who only has posted once. You are not ready for that. That is for the much more experienced.
3- If the provider is posting multiple times over a period then you have a better chance of not
getting into trouble.
4- Just before you call, take a shower and be ready to hop into your car and go. Most providers on Backpage are ready to see someone immediately. If you try to make an appointment for many hours later they will just tell you to call them again when you are ready.
6- Always bring your own condom. After giving them your money they might say they don't have a condom and if you didn't bring one then bad luck for you. No refunds. You'll have to settle for a quick handjob. If you're lucky.
5- When it's time to call dial the number and when they say "hello." You say
  "hello I was calling to see about setting up an appointment?" That's all you say. They'll usually ask for when and then you say "as soon as you are available." If they say I'm available right now. Then you politely ask "where are you located?" Always be polite and soft spoken. They are judging you by your demeanor. They will usually give you just a general location. Then you should ask "What would the hour be?" Don't say rate or donation or how much.
  Just say exactly that. If they say "I won't discuss that" then don't push the issue and say "I understand." Then once you get there and call again they will know you are serious on seeing them and give you their exact location. Then when you call once you are at the usually cheap motel you'll call again and they will give you the room number.
6- A more experienced Hobbyist will know when to ask about the donation, meaning providers rate. However as a Newbie you have no experience with this. If they won't tell you when you first called then they probably won't tell you until you are up in the room with them.
7-Once you arrive at the motel drive around the motel parking lot and look for anything suspicious. Anything that makes you a little concerned that looks out of the ordinary. If it doesn't feel right then leave. If they call you back and want to give you a hard time tell them you apologize and tell them something like you just got a call and have to go back home.  
8- If everything is good after the drive around and you have just called and gotten the room number. Then park in a well lit close to the front and able to exit parking space. Hide any valuables and don't bring anything in the room with you other than only enough money to cover your expenses, a bottle of water for you, your cell phone, and a condom. Don't bring I.D. a wallet or jewelry or any other valuables. I'm not trying to scare you but just be safe.
9- Knock on the door. Once they open the door it's time to put your big boy pants on and make fast decisions. If you are not happy with the person who opened the door. Maybe they are way different than the person in the photo and you don't want to have any sexual activity with this person then do not walk into the room. Tell them "I'm sorry I left something in my car and walk, don't run away. Then get into your car and leave. If they call then answer and say you are sorry but you got nervous because she wasn't the person in the photo and you are brand new to this. Be apologetic so they will not continually call because they are upset you wasted their time.
10- If you like their appearance then walk in. You then say hello and put your water bottle down on the closest place. If the T.V. is on then have the guts to ask if we can turn this off. Otherwise they will leave it on and it will be a huge distraction for you, and she'll focus on it rather than you. When the T.V. is off ask her "how Are you?" Then get close to them and look at them and ask politely "are we cool?" When you ask that look at them and it is not going to keep you
from getting arrested if that is the case but at least you will break the ice and get things going. Spending fifteen minutes because you don't know how to procede to the sex part will cost you fun time. When you ask "are we cool?' get close to them and they will usually want to let you know they are cool and believe it or not put your hand on their shoulder and then move
your hand down to their hand and move it towards the outside of your pants where your crotch is and at the same time they are about to touch your pants touch their breast on the outside of their shirt. This is meant as a super fast ice breaker. Remember it's time to step up and break the ice. Otherwise you'll be nervously talking forever and burning precious time.
11- Once you both know you each other are cool then ask politely "how much for the hour?" When they tell you and you feel you are willing to pay that, do not pull out your money yet! Once they tell you the rate then you let them know what you want as far as sex things.
The reason being once you pay them and it's time for action they may tell you when you ask them to do someting "oh no, I don't do that." So before you pay once they tell you the hour rate.  For example tell them "I like to get oral and I like to fuck." That would be the time if they were not going to do that they would say "I don't do oral." Then you say "I'm sorry I was really hoping for oral, that is a big reason why I came here." If they say no then say "Well I'm sorry things didn't work out." then you leave. If they say they agree then give them the money. It's best to have a rough idea of how much it's going to be and have that exact amount in your pocket for you to pull out and hand over. If you pull out a wad of cash it will give them upsell ideas etc.
If you need more money then pull it from another pocket. Don't show them how much you have.
12- Don't hand it to them just lay the money on the dresser. No envelopes with fast website ladies. They may or may not count it. Once the financial part is taken care of ask if it's cool to get comfortable. This is when it's time for both of you to get naked and do your thing. Don't be shy.
When it comes to doing anything sexual or non sexual you want to do. ASK!! If you don't ASK they won't do. Man up!
13- Once you are finished then get dressed and thank them. If they ask for a tip don't feel the pressure of having to give it to them if you don't want to. If you get nervous even though you don't want to give them anymore money and don't have the nerve to not give it to them then hand them a twenty.
14- Remember regardless of whether you had a good time or bad time always say "thank you." They have your phone number.
This is not every detail but hopefully it will help you get on the right track for those of you surfing the fast sex risky sites.

This is exactly the kind of example/tutorial/walk through I've been looking for.  Well written and very explanitory.

on the subject of unreviewed providers. Newbies are gonna try them anyway, so they might as well hear how it's done.

A few comments...

1-"Too good to be true" applies especially to the photography, NOT necessarily the girl. It may take a bit of a trained eye to make the distinction. If the pics look like they come from a magazine or an internet model's website, they probably do. Moreover, if the ad shows her rate, and it seems way too low for the girl's looks, that's also "too good to be true".

Beware of ads that are too explicit or suggestive. Legit girls tend to be more discreet.

Of course, always google the phone number and text from the ad, and check the pics with Tineye for signs of a scam or a pimp ring. Sometimes, this can also turn up good info you might otherwise miss, reviews, her website with rates, etc.

6-When you call, simply ask "What would it be for an hour of your time?" Keyword being "time". I've never had a legit provider balk at this.

10-The "ice breaker" is sometimes called an "LE check", which is bullshit. It doesn't prove anything, however many BP type providers mistakenly believe it does, so just play along.

11-14-Dude, you're more brave than I'll ever be. I've never ventured that far, but thanks for sharing.

beautiful ladies advertise on the site because it's the only game in town.

I used to use CL (before it was railroaded into closing its adult section) and BP before I semi-retired. I ended up with some great clients.

I also turned down a lot of so-called gents who wanted only fast-action, SW-type gals. I wasn't one of those and got some derogatory emails as a result.

But, yes, as a Newbie "tutorial", it isn't that far wrong.

but this is close enough to get an understanding of what to look for.  Many respected providers advertize of the various sites...  but the ads are mixed in with untold others who are not reviewed.  It is easier to START your search here on TER...  and peruse the links to the ad sites...  Than to start on the ad sites and research several to find one who is well-reviewed.
Once one arroves at the ad site...  lacking a web-site with a photo album...  I look for more ads with additional photos from different angles.   I want to be attracted to her but MORE IMPORTANT, I feel that a generous photo referance gives me confidance that it is the real person.  
A Newbie really should stick to well-reviewed providers.   Once you have a feel for how this works...  there will be plenty of time to go out on your own.

AKA: Enter.

Dang man, FORMAT YOUR POSTS!  What's an extra space?  Well, it breaks up the paragraphs!

point #3. With Backpage, you can set it up to automatically repost an ad several times. The lady may not actually be attending the ad and might have just set her ad to automatically renew every 30 days. So I don't think it means she's more reliable, I think it just means she wanted her ad automatically taken care of. This doesn't really tell you if this will be a cash-dash, LE, bait-switch etc. especially if she has no reviews. I have heard of LE doing this and as soon as a bust or so goes down, pulling the ad.

Personally, I've found the best way to go about BP is to do a search for the number, see if it's on TER and go from there. Also looking the pics up on Tinyeye to see if they are used elsewhere. But to each hobbyiest his own level of comfort with TOFTT!

Again great post. Happy hobbying/ providing!

great post...the to good to be true pictures is right on the money...i was burned with the same thing on eros...unless the person is reviewed her you are flipping a coin as to what person will show

these are great tips.

What I do is also look there number up on 411.com . If they are out of state chances ate they are not LE. I am not a fun of seeing someone with a number that is within the same county as me or the one right next door.

Thank you to the OP and the other posters in this thread. There seems to be an assumption here that TER is used by everyone everywhere. Some areas just don't have well-reviewed providers.

Why is it that so many providers have phone numbers from different area codes? I was actualy parinoid about that when I first started looking through ads trying to find my first newbie friendly young lady.
