Create a top class auto checkout bot for specific Shopify sites, supreme, and palace

I want to create an auto check out bot that will automatically check out multiple keyword-specific items as soon as they drop. Once on the page of the clothing I want the bot to have all the information pre loaded so that it can select multiple items, the size of size/quantity of each item, add to cart and complete the entire checkout process with credit card info and shipping and billing address. I want a bot for shopify sites, ftp/palace/hufworldwide (all on the same platform), and supreme. Heated sneaks is an example of a competitor. [login to view URL] Im not sure what time this will take to build a bot like this but I want it to be lightning fast to beat the existing bots that are out there. So please bit your most reasonable price even if it is outside the budget.
