A friend of mine who knows that I dabble in crypto asked me about NFTs, and after I explained them, he asked me if I could make his photography that he sells into NFTs, in exchange for the commissions from his sales.

First question is, where would you recommend minting NFTs?

Second; If my understanding is correct, then NFTs value is based off what someone paid for it...duh... But if I am going to earn the commissions, then I need to be the creator/origin of the NFT, correct? Then how do we set the price? Would he have to "buy back" the NFTs, so that they would have his desired price attached to it? And then I would just give him back the money?

Any help would be greatly appreciated! Thank you all in advance
