Start off your project using the contract that @coolcatsnft used

Solidity Contract Template based on CoolCatsNFT @coolcatsnft

The CoolCatsNFT contract is very well written and very gas efficient. Consider using this approach if you're creating NFTs off-chain. Can cost as low as $100 at 14 October 2021 ETH Price of $3,527. CoolCatsNFT team deployed this contract for $55.59 at $1,983 ETH Price from 27 June 2021.

The trick is to just use _safeMint without using _setTokenURI at all. Hence no ERC721Metadata.sol imported. tokenURI function will just concatenate the baseURI with the token id when calling the function.
