Photography

Hi, hoping somebody can point me in the right direction here. I am a filmmaker working on a movie about the cam girl industry. In the film our main character signs up to a cam girl website. We are building that website and need to source photos for the homepage of various girls in lingerie, nude, topless, etc.

The issue I am having is all the stock photography sites I am checking have restricted use clauses such as "You can never use iStock content for: Pornographic, obscene or libelous works" or similar variations.

The film is not pornographic but the industry and subject it addresses is. So my question is are there any stock image websites that would allow such use of their images? Or is my best bet trying to find a photographer who takes such images and making a deal with them? This fake website only appears for a few seconds in the film so though I am happy to pay for the rights to photos, it is not something I want to blow the budget on or spend a lot of time trying to sort out. Any suggestions welcome.
