A few years ago I was in the similar situation like you. I had idea, but I didn't have any knowledge about crowdfunding, so I had to learn that the hard way. Despite this my first campaign (book "How to Start a VoIP Business") was successful and I raised 243% of my initial goal. The result was AU$ 12,191 and 200 backers from 35 countries worldwide. Later I published this book in Amazon.
After this experience, I got really excited about Kickstarter. I participated in a few projects as a collaborator, which helped me to practice what I’ve learned and make sure this actually worked in other campaigns. I also interviewed more than 30 Kickstarter project creators from different fields. I wanted to learn their mistakes, tips, dos, don’ts, and key factors to success so that I could share this knowledge with you.
