ERC721,1155 Smart contract developer is needed

We need a smart contract developer to develop a contract - Contract should be Upgradeable - Allows multiple NFT's (ERC1155) to be locked against another NFT (ERC721). - When locking the ERC1155 it should have a vesting period (that can be set) - When it's gone past the vesting period who ever owns the NFT (ERC721) is allowed to claim that 1155 token and have it come back to their wallet. - Contract should support delegate.cash as well (for the owner of the ERC721) We need to develop a engineer urgently.

Thanks
