Here's what I'm thinking:
Customer would supply the binding fabric, either pre-washed or not, as customer chooses. I would give guidance on the yardage needed for the size of quilt. I would cut the 2.5" strips on the straight grain, do diagonal seams.
Machine stich to front, hand stich to back.
After Googling prices, I think my dime per foot is low.
Any other thoughts?
