Would work similar to Kickstarter but instead of cash, people/companies would volunteer lab or needed items
Posting a project would include all the background about the person and the project via text and/or video. Instead of funding goals, they would list the amount and type of labor and any physical items.
There would be rewards based on amount of labor or time donated
It could be like a membership site which part of a members profile would include expertise, knowledge and physical items they have available. It would also include any conditions that must be met, like a certain geographical area, or type of project. Project managers would be able to search the membership base to invite people with desired skills or items.
