Smart contract developer for NFT marketplace on polygon net.

We are looking for the smartcontract developer who can build contract asap in few days for NFT marketplace on polygonnet.
Our team has already contract developers, but they are working in other part for contract such as staking, bridge, etc.
For now, only for NFT marketplace contract is required for crypto-gaming on polygonnet.

The marketplace contract should :
- be linked to a specific erc 721 token so we can reuse the logic for nano nfts and helms (must have NFT address as field)
- contain a map of tokenId to listing price
- check for tokenId owner with the NFT contract before accepting changes to listings
- allow rightful owners of tokenIds to set a listing price. Either a new one or edit the current one
- allow rightful owners of tokenIds to delete a listing
- allow listings to expire (optional)
- allow anyone to purchase on a listing price. The tokenId should then be transferred to the buyer and the money should go to the previous owner of tokenId
- pay out royalties to the token contract
- Unit test

Note:
Please only apply if you can do this in this week. we know there are many lots of contracts already which you can refer and already done.
You must be familiar with standard NFT contracts and fast development.
Video call is required.
Thanks.
