You can get money to make a movie by participating in some personal fundraising activities, such as bake sales, car washes, odd jobs around the neighborhood, and yard sales. These may sound childish and insignificant, but when these things add up, you could get enough money to finance your own film.
Before others will loan money, you need proof of skill and reputation. 1. Hire yourself out to do documentaries for organizations. 2. Create video diaries for people for pay.
