In your situation, I would find it much more fun and interesting to offer to teach those moms how to make the quilt. You could give them a list of all the supplies, tell them where to purchase,maybe you could offer to buy a quantity of batting or backing and pass the savings along to them. Offer to teach them (as a group) how to make a basic quilt. Give them two dates when you would be available, and if they are really interested, they will figure out how to do it. You may get some quilting buddies out of the deal. If there are steps that they don't feel up to (quilting or binding) you could offer to do those for an hourly rate that you specify in advance-- say $10/hour.
