hey marie,
its really never to early to look for money with financing an indie film. you just want to make sure that before you actually present your plan, you have it all put together in a marketable way. As far as info about funding, i would definately do plenty of research. Read some good books on financing and how to write the appropriate business plan, try and contact an accomplished or experienced producer that can give you some pointers. I know of some good books but im not sure if im allowed to post names of books here. PM me if you would like any suggestions. good luck!!
