Hi @torek, it really depends on how you want to structure it. People typically act in their own self interest so you are going to have to offer them something in return. 

It sounds like you are looking for collaborators. If so then you will need to entice them to collaborate, i.e. are you going to pay them in either fiat or crypto currency? are you going to offer them equity in your venture? are you going to offer them a revenue share scheme once the product is launched?

If I were you I would try to figure out what the resource requirements are and have a clear description of each of those roles. Then I would decide on how to acquire those resources per the mechanisms I outlined above. 

Once you have that then it should be pretty clear on how you need to proceed in terms of investment etc.
