I've been on OMP since 2001, used to use it to book shoots/tours through major cities where I'd do 2500-3k per week, but then I decided to get naughtier and keep it exclusive to my site so I stopped .
No way you'll make that booking off OMP, especially for softcore
Mostly amateur photogs looking for tfp ;- and even the serious ones won't be paying that.
