This was well over a decade ago, but a former friend was a female escort for a few years and it was very different than what men go through.
It's a very different process and required vetting by either recommendations from other providers or providing of identification. She made 6 figures doing it, starting off at 300/hr and then I believe went up to 500 or 600, and apparently that wasn't usual for women.
There are a LOT more risks for women though as some guys can get rude, aggressive, and even potentially violent, hence the vetting. Also no in calls for first time hires, ever.
