NFT e-commerce

We did a website from a guy from Fiverr, who was not able to make the store working. We need some technicians who are able to make our website an NFT store, so that we have all the necessary plugins for minting and purchasing NFTs, such as wallet connect, buy now buttons etc...and the integration with the binance smart chain.
We already have a website, we just need someone that could improve it and make it a functional NFT store, nothing more nothing less.
