The usual process with working a project is:
1) Goal (a final version of a video)
2) Requirements (script, voice over, music, sound effects, animator, it)
3) Solution (as the project manager I would find the talent, deal with negotiations about price, and deal with it from my account so you need not be bother with it).
4) Complete (Yay!)
From big projects to small projects I have Project Management experience with a web app and website developer department.
