Hi,

Please make a quote for the following

I need to move this collection from 1155 to 721 and start the sales on 721, with the ability to add more NFTs on daily basis to the same collection and contract

[login to view URL]

1) I need to upload my NFT on a daily basis to ipfs, then also upload json metadata to ipfs

2) I will need to go to etherscan and mint NFT daily from there using ipfs metadata hash

- Once an NFT is minted, Opensea will display it under my collection, people can then purchase it from there.

Your deliverables would be:

- Smart contract ERC-721

- Assisting in smart contract deployment & verification, make sure it will be verified with no issues

- Opensea integration

- Showing me end-to-end minting process for couple of NFTs

Beceriler: Solidity, Smart Contracts, Ethereum, Blockchain, C++ Programlama
