Twice.
First was via a general ad on CL. Vacay to Orlando. "Interviews" themselves were quite fun. The final candidate was a 20-something, never been to Disney and stuff. Week long. Asked for 500. Then didnt want any at the end as I had paid for room and board, rides and gifts. Flight tickets of course. Gave 500 anyways. Beyond worth it. Stayed FWB for awhile till she moved to LA.
Second, via CL too. Long weekend (4 days, comped suite at Foxwoods, with all the fluff). "Gambling money" only, 200/per. I agreed, she was wubbucked to the max! She won big on day 2 on the slots and treated ME for the next couple of days, lol!
Both were girls I'd never met before, but chosen after "interviews", so I had some kind of an idea. Or not. As I felt that the "service" was, truly, above and beyond.
Lots of fun, especially as the second girl called in a girlfriend, also bi, on days 3 and 4.
Near dead at the end of both trips.
I'm sure that you will score real big on SA, unless you already have someone in mind (lucky girl!)
Prostitutes? Hmmm, I dont know, they seemed semi to non-pro. Maybe I didnt really answer your question?
