Start with a buying club. Go into your kitchen and pull two funnels out of the cabinet. Place them pointy ends together. This is your organizational structure. Notice that the places where the funnels widen out are two distinct places and may even be two different sizes. These are the bottlenecks where you need two COMPETENT people (no BS, no whining, no "I'm too tired to do my orders"). One of your gatekeepers/bottleneck facilitators handles the orders from the consumers and passes a compiled order to the other gatekeeper who spreads them out to the producers. The days to order, pickup points, cash handling, etc. are all just logistics. If you have two competent gatekeepers, it doesn't matter how spaced out all the consumers are. The advantages of a buying club over a co-op are simple - no brick and mortar issues. PS: You need a $50 buyin to handle shrinkage and waste.
