All of the following methods of raising money for your indie art film biz are fine: self-financing, using money/pay from other work, crowdfunding, investors, grants, donations, making movies for $0, using profit from your film biz to make more movies, selling merchandise related to films...
Or one can try to work for a studio, work with other producers, work for a TV network, etc to get the movie or TV show made & out. You might not fully own your work through this route however.
The important thing is, with digital video & the web where it is, it is now possible to make & distribute movies for $0 if you had to (grab your iPhone, grab 2 volunteer actors, shoot a short, upload to Vimeo or YouTube, promote it through social media, etc). Also, if you want to take the time to do so, you can spend a few years and raise a couple of million $s to make & release a movie w/ known actors, etc.
Making a good movie is always a challenge. Making money from movies is always a challenge. But, if you want to make movies your art work, & then make that work available for people to buy & or check out, it is possible to do so now, for we live in the Glory Days of Indie Film.

Examples of how I will use this new reality, how I will use these Glory Days of Indie Film to make & release my own movies in 2014 are coming up. In the works - 2 new features (Breakthrough Weekend, Brooklyn Fantastic), film festival submissions, a week long run in NYC, a possible film screening series and very rough ideas for a possible film festival, increased presence on the web re: my film work, increased marketing & advertising in the regular world re: my film work. Details & links as they happen. I am going to make 2014 a breakthrough year for my indie art filmmaking & distribution work :)
