I was approached by a screenwriter who's interested in putting together a treatment for an adaptation of one of my novels, which we would then partner up to pitch to studios. His resume indicates he's fresh out of Academy of Art University. He also says he and his partner have just signed with Intellectual Property Group. Since I have little screenwriting experience, would it be better for me to pitch with a screenwriter, or do studios usually have their own people they like to use, meaning I'm better off pitching alone? I'd appreciate any advice.
