Looking for a Backend developer who has Ready made backend for NFT website

We have frontend ready for our website for nft art and looking for a developer who already has nft backend and dashboard so it can be connected with our website, please be noted we need a complete solution which has a marketplace, collecters dashbaord, artist dashboard, minting of token etc.

I am not looking for a person to develop backend from scratch i am not interested, if you have a readymade backend for nft only then bid on this project.

Thanks
Note: to make sure you have read this project thoroughly and had ready made backend to show write "I have Ready made NFT backend" at start of your bid
