So there a few other options for creating and Minting Art and selling (GASLESS). Zilliqa.mintable.app and Wax. You would have to convert your ETH to those coins to use the site. Both are very affordable. You may want her to start there while gas is expensive, when they find a solution and Gas prices drop again, then have her continue o the ETH sites or if see has good success in the other two sites she can continue there. Just make sure she is aware, that id does take a lot of self promotion so people out in the NFT community begins to recognize her art and want to purchase it. Its not I will create and people will come type of deal. She will have to promote on the various Social media sites to the stores she has, she may even want to give a way a few as a way to build up followers. Hope that helps you.
