Heya. I've done both. My first movie in the US " Devil's Cove" I self financed completely and we shot it on the shoe string budget of $10K. For Introducing Jodea I had 2 other friends/ investors who came on board with me. It's always good to find people to invest with you but sometimes if there's a project you're truly passionate about and nobody wants to invest.- the only answer is to do it yourself. Crowdfund. Save your money. Whatever works.
