NFT Project

Hi everyone, I would like to do something very simple. I would like a website that allows me to record voice, or where I can convert audio files to NFT. Users will have to pay in BNB for each conversion + the usual fee of the binance smart chain network. We need to create the code that I will test with version to embed it in google sites before buyng domain. Once I have bought the domain I will need to link the code to the website (you will have to do a simple frontend). Remember that in order to use this function, users must pay, so they must be able to use their wallets with the website. Please read what I need before bidding and propose only if you have adequate skills. Thanks in advance.
