Though your main film funding should probably come from proper investors, grants, loans, and other forms of organized funding, the independent world is never perfect and getting all the money you need is rarely an ordered process. Luck and ingenuity play into the funding process quite a bit and it is up to you to use connections and creativity in a way that can get money to fill the gaps. For some of this you can look to past incarnations of financial acquisition, especially those that go along with fundraising.
