Modify ERC 1155 Sample Contract: Add Escrow & ERC20 fungible functionality (Solidity & Ethereum)


I'm in need of a solidity developer who can customize the existing ERC 1155 contract on openzeppelin to include both fungible and non fungible (erc 20) features.

Here is the template I'm using from opensea: [login to view URL]

Since I will be importing my token on opensea after deploying on mainnet, here is what I need added to the existing template:

- Add ERC20 token functionality as well within the same 1155 contract (use our own token with the specifications we provide)

- Add/customize a atomic swap/escrow feature to approve task/function from specific wallet signatures.

I need someone to quickly help with this since I'm familiar with solidity but need an additional hand with someone who has more experience with the recent updates on the NFT standards. Please bid if you have experience. Thanks
