I believe that the solution could be to try to find collaboration in a liquid organization like ttps://assembly.com. I think that it's a good model exchanging labour ( instead of funding ) for shares. I haven't joined any of these projects yet for two reasons: I am not excited by the one already available and was focused until 1 month ago on my new app for iPhone which unluckily is not going well from a sales perspective even if the little feedback from users is positive. Good luck with your venture.
