I've found New Crowd Funding website based in the UK, called Sponsume.com. It's Free to use and is all or nothing funding, similar to Kickstarter in the USA. That is you only get the money if you reach the full target in the time you pick for the project.
Rather than offering investment in your movie or project, you offer rewards, like signed DVD's, Tee Shirts, Producer credits or thanks on the movie credits.
I have started a project to try and help with Self Distribution funding for the Film premiere and the URL is http://www.sponsume.com/project/pub-crawl
Check it out and you can use it to get on guest list for Pub Crawl Film Premiere, if you can get to London on 29th March 2011 and fancy a movie, a band and some beer.
