wooo interesting story.. even though, we work on the same industry.. I never knew the industry dark side before.
I am just wondering why you dont ask for their folio, cv, and interview them too? or at least have your agent to do interview with them.
You can tell from there if they are good enough then they shot big fashion magazines and we all know only few photographers on the local market that only can do that.
btw, I am also on the photographer side and I do casting most of the time..usually, need to explain my concept to the agent or the model before to do the works even its only for a test shoot and no..i almost never think to sleep with my models. Most of the time having great result are more satisfying than orgasm it self
