Well, you know what they say, if it looks too good to be true, it probably is. There have been sites like this before that copy & paste providers from other sites around the US & world. I've never known them to be legit. If there are that many providers displayed & you don't recognize any of them, chances are good that it's bogus.

Never heard of the agency and the photos look like file photos from somewhere else. I agree, if it looks too good to be real it's probably a fake.

. . . has the time and resources to TOFTT?

I'm pretty sure they are fake.... I've never seen classifications of Asian, Busty, or Cheap..... lol  You may not want to spend much money but I doubt you would call and say just give me the cheapest one you have

I performed three TInEye searches on photos of random GFE girls, and they all had hits on London agencies.  Isn't there currently a travel ban against non-US citizens from the UK?  My guess is you'll get penalized by an illegal substitution.
