create a page web to allow User to mint NFT (hosted in my database)

Hi, I need a webpage to allow User to mint NFT . I have the pictures (GIF) on my computer and guess that i probably have to transfer it in the database. Then Users should be able to Mint their NFT from my pictures trough Web 3.0 on Ethereum blockchain. Please feel free to contact me for more info. And have a look on similar webpage: https://killaznft.com/
