Hi HN!
We just unveiled a new concept. Crowdraising.co is like crowdfunding but with pledges of time, talent, and favors, instead of money, in exchange for rewards. Time can be used for customer development (surveys, interviews) bus. dev. favors (social media shares, introductions), or for talent acquisition (work samples).
We would love to hear what this community thinks of our idea, our meta-campaign, and any other feedback you can share. Please tear into it, nothing would make us happier.

Busy people tend to trade money for time. Not so busy people are often not so busy for a reason. Moreover, professionally competent people tend to have no shortage of opportunities to work for free.
Anyway, it is an interesting idea. I think the key bits are building an economic community and creating trust.
Good luck.
