I designed a pleasing arrangment on a door of a truck for a customer's business and he now wants that embroidered on some beanie caps and some shirts now. I did saftey green shirts with D&T for the customer (silk screened), but now having a hard time getting the embroidery work down as i haven't found a source yet. I know this goes out over my head, but I'm about to supply the costomer with the file. If I do that, what should I charge for it?
