This is for people who have a very large collection already minted on polygon and want to list them all for sale. This is not for uploading new collections. Writing your own smart contract and minting thousands of items on polygon is fast and simple and you don't have to care about captcha getting in the way, but then listing them all for sale? That's not easy, nor quick - BUT this solves that and luckily, as of now, opensea has no captcha for the listing for sale process.

Also - if you dont own a few in the series of numbers, or have them already listed, it will automatically skip and continue on in the process!

This code is heavily inspired by a few others I've seen around github that did the full upload process, but captcha issue pretty much makes them all useless. Mint your own contract and use fractions of cents to mint your entire collection. Doing so with polygon MATIC is not that hard of a process it turns out.
