most of the porn stars who use ImLive to chat with their fans and admirers have a website link to either their agency or their website(s). Also the Porn Stars who advertise on Eros usually have contact info, regardless of if they use an agency or not, you'll be appropriately directed.

Just tell her what you want and ask her rate for what you seek...expect to pay whatever the girl gets paid to do a photos or video for the production companies & studios.
