Read the newbie board thoroughly, tell us what type of lady you like, your situation, what are you looking for, yadda, yadda.

Search reviews for the area under the demographics that get you all hot and bothered. Also researching how to contact a girl and get screened would be helpful because many guys get turned away when they are new because of how they interact. I myself will see a new guy but I go off of our conversation together in addition to researching your info for my safety. If a guy isn't respectful and kind via email I feel he won't be that way in person. Best of luck.

At this stage one of your primary concerns is to develop references. Be prepared to offer some work info to be screened for your first date. Don't be afraid to spend a little more your first time.  

Find a provider that is well known. One that has frequent ads and has recent reviews.  

Providers that post on the message board are usually "quicker" in providing replays to future reference requests.  

Ask what their policy is for giving you a "white listing"

Write a review as soon as possible after your session.
