NFT, Smart Contract, Solidity Developer Needed

After deploying our smart contract for an NFT collection, we have encountered some issues with the visibility value on Opensea of most of the NFT we minted so far. We need a developer to assist us with fixing some issues.

Very important, We need someone RELIABLE.

You must have experience with Smart contracts and NFTs.

I am probably estimating a few hours of work for this project.
