Hi, sounds as if you would benefit from books like The Guerilla Filmmakers' Handbook series by Chris Jones; Business Models For Filmmakers by John Sweeney and how to articles from places such as Raindance. If you can, try doing Chris Jones' Guerilla Filmmakers' Masterclass that takes place in one weekend, or his ongoing online course about his Oscar shortlisted film, GONE FISHING. I would also recommend attempting to make short films by any means necessary, on low or no budgets, including on your smart phone and building up from there. There is NO substitute for doing IMHO. Good luck!
