Bringing it all together - crowdfunding meets freelancing - repost

At present sites such as Freelancer enable people with ideas (like me) to link with people with technical skills (like you). Unfortunately, for the process to work the people with ideas need money to pay the people with skills. What if there is another way to bring ideas (and businesses) to life? I want to bring ideas, money and skills together in one place. Crowdfunding meets Freelancing. A place where project collaboration can occur, through ownership sharing rather than direct hire / fee for service. I don't want to re-create Freelancer, or crowdcube (or similar businesses) - I want to hook them together, with a mechanism to control the relationships, and provide value-adding services (such as NDA's, corporate structures, revenue handling and distribution etc). Tell me how you would do this.
