You want a script, well the first question I pose to you is: what are you looking for? Do you want comedy, drama, sci-fi, horror, thriller, action, etc? Not only will you be getting a script, but you will you would be getting character bios, step by step outlines of the story, and a beat sheet giving you the breakdown of major plot points. I would work with you to make sure that you got what you wanted so that you are happy with the finished product.
