Need help boosting my Kickstarter pledges

I am currently running a Kickstarter project for a book that has $6800 raised ([login to view URL]). It is a collection of comics from my webcomic ([login to view URL]). I have already reached out to my Facebook/Twitter/Tumblr followers and cannot figure out how else to market it. I would like to turn this into a $30,000+ project by the time it ends. I need someone with great marketing ideas, whether that includes advertising, videos, web design, SEO, or whatever (I have NO IDEA, which is why I'm asking for help.) If you have done marketing for crowdfunding projects before then that is a plus. I am worried that since this is such a small niche (people that like my webcomics) that it would be hard to market. Many projects can be sold to anyone, but a webcomic book generally requires the buyer to be a long-time fan. So I am not optimistic, but if you think you can make it happen then please contact me. A few helpful notes: The creator of a much larger webcomic is writing the foreword for the book, so if I could reach his fans that could help (he hasn't tweeted about my project or anything and I don't want to ask him to.) Another pretty big website is doing a guest comic for my book and again, he hasn't notified his fans, but if I reached them they might be interested. Also there are a decent number of people on 4chan and Tumblr and other parts of the web that have seen my comics but don't know where they originated, since my comic pictures don't contain a web address in them. I'm honestly not too optimistic that I will find someone that can help me, since books like these can be hard to sell to new fans. But if you are able to come up with some ideas that get me excited that would be great!
