Questions about selling content

I am a photographer in the Dallas area. I have a client wanting me to shoot her for porn sites. I don't know yet if she's talking about BG, GG, or solo but we will get to that. I also don't know if she wants to handle the shots herself or if she want me to sell them for her. What do I need as far as releases etc.? Also, who out there might be interested in buying them? I know you want to see samples. Those will be up soon.

Next question. I've been shooting nudes for 30 years. I have many sets available but the releases were from the old days when all I needed was a signature on a model release and possibly a photo of her drivers license. Can these be maketed or am I sol?

John.
