Someone wants to buy my art as NFT. Scam?

Someone says they are a collector of NFT and has seen my art and is asking me to mint one digital art he wants to buy for a significant sum. He thinks he can resell it for more soon.

It seems personally as an artist my own risks seems low: the nft site charges a few hundred for the "minting" and the buyer would immediately buy it. Worst case i might lose the mint fee.

He says he wants to buy several pieces but I'd only mint one until i get it sold, before doing anything with the next one.

Seems like the risk is on his side, but... Am i wrong? Am i being scammed? Should i risk it?
