NFT project

We are seeking programming work to develop an NFT Solidity contract for 10,000 NFTs to be deployed on the Polygon network. The contract must be fully compatible with OpenSea and Rarible, and must adhere to the specifications outlined in the OpenSea Polygon Basic Integration documentation. The contract must be ERC721, ERC721URIStorage, IERC2981, Counters, and Ownable, with a royalty payment of 5% (500 points) included. The counters implementation must match NFT .png file numbers, starting from 1 to 10,000. The contract must be MIT licensed and created in logical blocks using separate .sol files with imports for clarity of implementation. To create the contract, you are free to reuse or copy any existing NFT contracts from polygonscan that are MIT licensed. However, you cannot copy any existing code that is not MIT licensed, and we will check for code matches with existing contracts. The contract must be delivered as a complete package that we can compile using Remix online with remixd local files, and must compile without errors. The contract should also include on-chain minting via Remix, direct minting on OpenSea and Rarible, pause function, and the ability for the owner to batch mint at any time. We have test files AAA with CIDs for .png and .json meta files on IPFS, which will be replaced with actual files BBB in the full deployment. The project will have two stages. In stage 1, we will deploy the contract on the test Polygon network with AAA files to ensure that the implementation on OpenSea Testnet is correct. In stage 2, we will deploy the contract on the main Polygon network with AAA files and test its correct implementation on OpenSea (mint, buy, sell, bulk mint, etc.). Upon successful completion of stage 2, we will approve payment for the project. Finally, we will compile and implement the same contract with BBB.
