It is not easy. Or cheap… I have created NFTs on Wax and a few other places. It was very expensive… I have sent messages to OpenSea , Super Rare, LooksRare, Raribles, CoinbaseNFT, BinanceNFT to see if there is a way to create NFTs for free and pay a % when they sell … so far no replies … the last time I created an NFT I had to pay Erhereum every time I clicked a button. Kind of a disaster …
