My LAQ offers a binding service which I occasionally use because I have arthritis and just can't get my hands to work well enough to hand sew it on myself. She charges a set price based on the size of the quilt and she furnishes the thread. She also guarantees her work and gives a specific date by which the work will be completed.
Because I want to know exactly what the cost will be in advance of having the binding done, I would not agree to pay anyone based on an hourly rate . So, I guess what I'm saying is: Yes, I would use your service if your prices were fair, your work was on a professional level and you met the scheduled pick-up date.
