... this is kinda complicated... made more complex because you edited your initial post after I had already submitted my reply above.
First, you provided links to TWO ads. They do not to my eyes appear to be for the same provider. The first ad has the same phone number as is in Melisa's TER profile (
http://www.theeroticreview.com/reviews/show.asp?id=220613), but that ad doesn't include a name and has pics for a different woman/women than in the ad linked to in Melisa's profile. And the pics in the BP ad-with-no-name appear to be for other people, as I noted above. So that's strange, and a red flag... but legitimate providers have been known to put "fake" photos on BP. And, Melisa has 6 TER reviews.
Then, the 2nd link you provided is for Meela (
http://www.theeroticreview.com/reviews/show.asp?id=229842). The pics in her ad (linked to in her TER profile) appear to be of her, per Google Image Search--or at least, it couldn't find evidence of the photos having been stolen from elsewhere. And Meela has 3 reviews. And I don't see anything to raise a red flag on her web site.
So your post is confusing to me... you said "this person", but you gave links to two providers. You may have good reason to be wary of the client who contacted you, based on your communications with him. But I don't see how Meela fit into this, or why you are questioning her legitimacy. (No, I don't know Meela, or Melisa for that matter.)
Wouldn't the safe approach be to ask the prospective client to wait until you have been able to verify his references to your satisfaction?
