How would you recreate something like Kiva?

I want to have multiple projects where people can commit money. Once a set level is reached, everyone is charged and we deliver the product.

The idea is crowdsourced nutritional info. Lots of smaller restaurants don’t have nutritional info. This makes it really hard to eat there and still hit your fitness goals.

Letting people vote for and pledge money on various dishes. Once we hit $850, the cost of nutritional testing, we will buy that item and send it to a lab.

I thought about just using Indiegogo but managing a lot of projects would be hard.
