my post about Kickstarter back in January 2011. Authors have been using sites like Kickstarter for quite a while to fund their self-publishing projects. I've seen plenty of authors raise thousands of dollars through this "crowdfunding" model. Well, Rich Burlew recently raised a million bucks through Kickstarter for his webcomic book. You read that right: One million dollars! Here's the story: http://www.guardian.co.uk/books/2012/feb/22/author-raises-1m-self-publish-webcomic.
Kickstarter's not the only player in town, either. There's a bunch of crowdfunding sites out there. Go ahead and Google "crowdfunding websites" and you'll find a nice list of options.
Why not give it a try?
