I would use this a a basis, and write up a contract with half down non refundable deposit and the rest on pick up. That way the customer knows up front what it cost you can even print this out for them so they can kind of have an idea how much time and labor and costs are involved. People usually expect handmade quilts to be 50-100 dollars, because of places like walmart that use cheap labor in places like china to get their product cheaply made. I personally will not work for sweatshop pay and my time is way to valuable to be underpaid. I make 30 dollars an hour at my job so why would I accept 2 dollars and hour for quilt making. Even at minimum wage here in CA which is about 10/hr you are still looking at charging them in the hundreds for your time 50 hours x 10 is 50. This is if they are providing all the materials. If they want an intricate quilt pattern they will be looking at more, as this is for a simple pattern
