NFT Website

Hi, I’m looking to have a website developed asap for an NFT collection that integrates with OpenSea.

Here are the requirements

1. Smart Contract Ethereum
2. Open Zepplin route
3. MetaMask integration
4. Metadata on IPFS
5. OpenSea secondary market integration including metada
6. Mint random NFTs via website
7. Website landing page - possibly 1 more page for unlocking rare NFTs
8. Pre-launch minting - NFTs revealed 24 hours after launch. Before that another image / gif / video will be the base NFT
