Look for ads where the poster has taken some sort of trouble or care to provide you either with information you need, such as services, description, location or to present themselves professionally: such as good grammar, spelling, actual information rather than "I am hot" (or in most cases, you will read: " i r hott"
First you have to decide what you want, what you don't want and what you can live with or without. They should make it easy to contact them, so the best thing is if they either provide a website or a phone #. Both forms of communication will give you the information you need to make a decision: rates, services, and something about the sp. If you can't get a straight answer about any of these, move on. There is always someone else who can.
If they post at 3AM, & you are not a "partier" avoid them. If you are uncertain about an ad, take the last 4 digits of the phone # and do a search. If you see many other sps under the same #, it is an agency. If you prefer independents, move on.
If it is an asian ad, assume you need to add 10 years and the picture is fake. If you are still interested, search the name here for reviews. It is rare that anyone reports a picture is real, but it is also rare that anyone reports that they had a really bad experience. You can be assured of all GFE services will be available for most asians.
For other ads, you need to ask about specific services that you are interested in, AND you need to confirm on the phone about the rates for those services before you get there. You can't assume anything but if you ask up front, you should reduce any possible "misunderstandings".
