I was contacted by someone that wanted me to make an item that they could then use for a mold. They would then sell the pieces made from my mold and send me a commission per item sold. They would like me to sign a "contract" of sorts ( basically saying they would pay such-and-such an amount to me, etc.)
Has anyone ever done this? Has it worked well? How do you even go about figuring out a commission price?
Thanks.
