"Have workers that can sign on to work whenever they have the time. The workers handle the orders and receive a cut of the fee you charge."

The problem is how do you pay such workers? If that's per order cut, they will want to make as many orders as possible inevitably degrading the service quality. And it usually takes a single bad experience to put people off of such service.. Actually, I don't see how this can scale well, imho, they should market more like "personal assistant on demand" and include monthly fees or pay per assistant's time, what also could solve a questions-that-do-not-result-in-order problem.
