Almost all ads explicitly listed the sex acts offered. People on there weren't even being discreet about it.
From glancing through the listing (on archive.org) I would suggest that "high-end" is inappropriate. It seems to include "high-end" escorts, but by no means be limited to them.
Unless, not being involved in any aspect of that trade, I just have a really wrong idea of what "high-end escort" means and the term includes those offering $50 no-condom oral sex.

LORELAI: Seventy-five thousand dollars. Seventy-five thousand dollars. Oh my God, that’s like 150 pairs of Jimmy Choos.
RICHARD: What are Jimmy Choos?
LORELAI: Shoes.
RICHARD: 150 pairs, that’s it?
LORELAI: Dad, they’re Jimmy Choos.
RICHARD: For seventy-five thousand dollars, you should be able to buy at least three or four hundred pairs of shoes.
LORELAI: Not Jimmy Choos.
RICHARD: But that’s ridiculous. You are not going to spend seventy-five thousand dollars on Jimmy Choos when you could buy four hundred pairs of less prestigious but I’m sure equally stylish shoes. You will shop around first. Is that clear?
LORELAI: Yes, sir.
