NFT marketplace on the Avalanche network

Im in search for a developer who can make me an NFT marketplace. Preferably someone who has previous knowledge in the DeFi space. I need someone that can do everything from backend to frontend to integrating contracts into the platform, UI/UX, and be able to work with ERC721 and the ethereum/avalanche chain.

Something along the lines of:
