How can I mint ERC-721 nfts hosted on IPFS?

I would like to mint images as nfts to ethereum. I considered minting them on opensea but two problems:

1. that would be ERC-1155
2. thanks to lazy minting, the nfts wouldn't exist on the blockchain until the first time they're moved (I want them to exist right away).

Is there a website or service that makes this easy?

I checked out minty which promises to do exactly what I want via CLI ("Go from nothing to creating a freshly-minted NFT token and storing it on IPFS with the help of services like Pinata"), but this also has one problem:

1. the instructions provided only show how to mint the nfts to a locally-hosted testnet, and I'm not sure how to point it to the real ethereum chain / Minty smart contract.

I had assumed there would be an easier way, a site with an OpenSea like UI but works with ERC-721 and IPFS.
