My son is an excellent designer. He doesn’t want to get into the needling part of tattoos, but he likes to make designs. Many of his friends seek him out to make designs that they can take to the tattoo parlors. He’s giving away his designs for little or no money. Can anyone suggest how he can market his designs for a fair wage?
