I know of a guy in LA who arranges some of these situations. It is all real. Funny thing is when they reject some girl who is super hot and they do it for a fairly trivial reason like hair color. The girls get so upset.
I know a super hot brunette who was rejected because they wanted all blondes. I think the going rate is $35k and it goes up from there depending on the model and how many disgusting sex acts she has to perform. Then these whores come home and find a beta male provider and he treats her like she is a queen.
