I'd highly recommend reading Jamey Stegmaier's book on Amazon about crowdfunding. Some lessons there are invaluable and easily overlooked by many people (Example: Try and pledge to at least 10 other campaigns on Kickstarter before launching your own). If you don't want to buy the book, many of his lessons are freely available on his website/blog. Lastly, while you might wonder why I'm suggesting someone who specializes in board games - his knowledge and lessons are easily applicable to anything.
