NFT minting website with Web3.JS and Arweave.js

Website to mint NFT tokens with customised metadata on Arweave (AR) for game. User logs into website with metamask via [login to view URL] Step0 - User pressing mint button to mint token from our contract ( only if user is whitelisted but this is already in contract) Once mint is successful user can fill in the form to construct their token data: Variables: NFTimage - option for image to be uploaded by user in png format or use default png - this option is user choice. (choice is required) About - max 200 txt characters.( required to fill in ) Content - max 100kb of text( required to fill in ) CustomContentupload - 1 file max 1mb ( optional for user ) (save button) At this stage we need to save above content on our server against user ERC20 address - whichever method is simplest ( probably json files will be best solution rather than mysl or txt ) - at this point user can edit all above. If user press "Submit" button then : Upload user data to permaweb we need to create json file from user content and post JSON and data to Arweave by using Arweave-JS ( we need mechanism which will stop user from using our AR funds more than once per token id or abuse this in any other way - to avoid keeping all the records in database maybe we can use call function to contract ReadTokenUri and if is not blank then allow user to execute Arweave-JS via proxy kind of method so our key is not compromised ) If upload was successful user cannot edit their data any more. If user has multiple tokens minted he need to have a choice to choose token on which SetTokenURI function will be executed - user can choose token id) - if try to setTOKENuri for token which already have TokenURI then error msg. JSON for upload should looks like: { "description": " Content ", "image": "ar://HASH/[login to view URL] OR [login to view URL]", "attributes": [ { "trait_type: " About " "value": " Title"}, { "trait_type": "My File:", "value": "ar://HASH//[login to view URL]" - if user upload content on website } ] } Contract is ready and have all functionality already what need to be done is the frontend part without graphic for above functionality and Arweave-JS logic. This is non profit project so budget is limited.
