hi i can help you with this .
i used another companys API for my cam site and i have the developer who did this for me
who could 100% help you out with this
please bare in mind this is not cheap and it quite a time consuming prosses , around 2-3 weeks also they have just launched there new mobile API as well so all your users can view models via there mobile devices
so its all good
API partners take a 47% fee from you
37% for the models and 10% goes to the partner
i was in your situation 2 years ago and took me about 1 year to find the ight company to do this
hit me up if you still haveing issue trying to source these , if you have already got the help you need then good lucjh and hope you do well
