Lead Team for Roblox Game

I have a complete, professionally-written Game Design Document and a total budget of about $3,000 that I plan to break into clear milestones. What I need now is a single lead developer who can take full ownership of the build while coordinating a small, reliable team... (Budget: $1500 - $3000 USD, Jobs: 3D Game Art, Game Animation, Game Design, Game Programming, Graphic Design, iPhone, Mobile App Development, Roblox, Unity 3D, YouTube Video Editing)
