What about this? just found it today:

It basically spreads your video around the net to help promote your kickstarter campaign.
Heres a couple testimonials from their site:
We were WOW’ed with the results we received with Virool! Our video jumped from 0 to over 500,000 YouTube views in one weekend
Mary Smith, Advertising Agency
Virool is like a PR company on STEROIDS. Our video ended up on hundreds of blogs and accumulated millions of youtube views. In short, "Virool is AWESOME!"
Jay Singh, Artist Management
I love the real time analytics and transparency of Virool campaigns. Our clients are always happy with knowing exactly who is watching their videos and seeing the views stack up
Jordan James, Advertising Agency
Of course I have no actual idea of how good it actually is but it could be definitely worth a try...
Its only a 10 dollar minimum start of cost anyway, but that is only for a viral video campaign that lasts only a short time, I guess you have to deposit more if you want it to last longer, which would potentially cut into the actual kickstarter...
EDIT: I also just published a ad on my turbosquid product page to attract some more backers from over there as well.
