Anything Goes : The Ellis Case by Godfrey B. Torrance

I am working on a short film I wrote, that will be shot this summer. (Late June - July). I am a student at The University of Alabama currently living in Suwanee, GA for the summer. I am looking to cast four main characters and some extras. I have a way to acquire locations, but will mostly need actors and a crew. Do any of you know an efficient way to gather these resources? Or do any of you have any interest in helping with the project? Any advice would be appreciated. Here is the logline the film: An 18 year old high school student searches for the son of his favorite author, R.S. Ellis, to see if he can uncover the true inspiration for his father's works, but what he finds is something he never saw coming. Thanks for any help.
