But I have not to be like a free offer, you can sell the business model to the developers and offer them a proportional share according to their contribution for a certain time window... Of course, most people don't do things for free, that's why I suggested to hosting a competition within some collages to offer one prize for the winners who manage to deliver the best products (way more cheaper than hiring actual pros and maybe a more efficient way to advertise the project and the platform as a whole)
