That would be a tough one for me. If they are really good friends, I wouldn't want to charge what it was really worth. I would give them a set price of $100 to make and machine quilt the quilt if it wasn't huge. I don't machine quilt huge quilts on my domestic sewing machine. Most people would even think you are price gouging at $100 if they are not quilters. I know that isn't very much but it is $100 you didn't have before and you can use it to buy more fabric.
P.S. they would buy the sashing fabric, batt and backing themselves so you would only have your labour.
