I have done machine embroidery for other people and have priced it two different ways. If your machine/software/design gives you the total humber of stitches in the design, I price it at $1/thousand stitches. I round to the nearest 500 stitches, making it an even amount. If your machine or design gives you the number of minutes it takes to stitch out the design, I price it at 50 cents per minute. I started out with a machine that gave only minutes and moved to one that tells me the total number of stitches, so the 50 cent approach may be a bit outdated. I do not charge for the cost of supplies as that is included in the total fee. Hope that helps!
