See. Figure out exactly what kind or role you want to play, be it a writer, producer, director, or all of them, and get some opinions on the best course of action from the people who've cultured themselves in the same way.
I'll take a look at what I have now and just send whatever, unless you can think of anything specific you want before I can get them to you. (Maybe you want to study the conventions of a certain genre, or the structure or character development of a specific film. That sort of shit.)
I can't really say. The capacity of what I want to do, and what you want to do, are two very different things. I know New World Order just graduated (cinematography)... I have no idea if Bonomo went to school. Disanti... Ask around. See what these fellows have done, what their thoughts are. Find a forum with a focus on filmmaking and get some feedback.
Do you have anything specific in mind, or do you want me to send whatever? A few every week? More? Less?
