music NFT platform development

i am just looking for whom have smart and strong solana/rust experience. at least over 3 years. we are building an innovative music NFT platform. Believe is one of the biggest independent music distributors in the world (they bought out Tunecore for 1 billion USD). our main goal is to build music digital service platform with NFT minting that is compliant with Believe's backend. NFT platforms like opensea, rarible, foundation is more focused on digital art but our platform would be very specific to music. basically we would need to modify existing contract code to create "NiftyTunes" while maintaining core functionality of it. candidates needs to know how to do on-ramp and off-ramp as our platform would let users purchase NFT in usd using credit card or BTC or ETH etc. for the right candidate, I will provide more detailed specs. thanks.
