I was approached by a friend to design a desk. It will be small-amount mass production. The price will be toward the high-end side. He offered three options for the fee, i.e. commission only, roylties only, or combination. I have a few questions, and wonder whether anyone could give some advice.
1. If he pays me commission fee, does that mean he will have the copyright of the design?
2. How much it usually charges for designing a piece of furnture like this?
3. If I choose the combination option, how much royalty I should charge?
Thanks for your help!
