If you do decide to proceed, make sure that you develop some sort of written work order: size of quilt, binding style (if applicable) color of thread estimated cost, estimated completion, who provided the binding fabric etc. When the quilt is dropped off, make 2 copies, keep one with the quilt & the other goes to the customer.
Many quilters do hate this step! It's worth at least investigating. You could get some brochures from local long arm quilters, and offer to work with the ones that don't offer this service.
