I think it's gonna be not too easy. A girl in the usa needs to make more money for her living, than a girl from Hungary. Most users look out for cheap performers who will do anything for 6 tokens a minute.
But sex still sells and if you have some really good looking and nice girls, people are willing to pay higher prices. So it all depends on the performers you have I guess.
