NB, if you've posted to ask whether Eros London is worth advertising on then fine (and I would say yes; I use the Visiting ads now and again).
If, however, you've posted just to gossip and speculate about how much work other people are getting on the basis of the fees they charge, a question that can only be answered by the people you're talking about, I suggest you contact them and ask. Why would anybody care how much money somebody else is earning?
