Hi Sin,
mrfisher is right, there are many of us here willing to answer questions from those new here. Pro pics are good, but many guys like candid shots, and with the quality of today's camera's, they are easy to get.
A website is always a good idea, just be sure to have all the appropriate info for guys to see, esp info about rates. Many guys are not comfortable asking about rates esp on the phone. So many times I have seen sites with wonderful pics, bio of the provider, calendar, etc, but for rates, it says 'contact me'. When I see that, I move on. If you post an ad on one of the many escort mall sites, be sure to post a name if you want a phone call for first contact. It's kinda difficult making a call and not knowing who to ask for.
As far as reviews go, any client you have seen in the last 90 days can review you. The first one will establish your profile and get you an ID number assigned by TER admin. Once you get a review you can ask admin to link your profile to your handle so that each time you post something, it will appear right under your handle. This will make it easier for potential clients to check you out. You can also ask for limited provider VIP, this will allow you to read the juicy details of your own reviews, but not those of others, that you will have to pay for.
Start posting on your local regional board to get your name out there and let them know a little about your personality.
Feel free to come back here if you have any other questions.
