I think that establishing the crew of people committed to the organization is key. Burnout can happen pretty early on and its important to have incentives or a conversation together to talk about motives for the project. Are you starting a worker onwed bike shop? or a volunteer-run collective? There's a pretty big difference in structure based on whether you're paying your staff or not.... Coop implies some sort of economic stake in the organization... like profit sharing. In our non-profit it's entirely volunteer run, and we call ourselves simply a collectively run business. There's tons of useful documents on the bike collectives wiki. good luck!
