We need a full stack dev who has ample experience creating erc-721 smart contracts. We need you to create and implement a secure erc-721 smart contract for the release of our Collectible Art Project consisting of ~15,000 pieces. Deliverables: 1. Random Generation Of Our 160+ nft traits onto our base bots. 2. Smart contract allowing users to pay for their nfts and then 0-10 days later receive their NFT air drop. 3. 3 % residual in trading fees. 4. Database management for the NFT art that is produced so that is stays readily available. 5.A Smooth No Hiccups minting process on launch day. And smooth delivery of the NFT on delivery day... Depending on circumstance these could be the same day or 10 days later. 6. A very simple website. Akin to BAYC and Wicked Craniums
