Create NFT Marketplace

Create NFT Marketplace for selling NFT photos/music / video. Looking for an expert to help us setup an NFT marketplace similar to Opensea and Foundation for listing and selling NFTs. Need an expert to help us who had experience in this sector. Please only apply if you have some experience setting up the APIs etc and know what to do to help the project go smooth and be successful. Looking to get started ASAP and have a long term partner to work on with this together.
