Restock monitor for Shoe sites

I am looking to create a script that runs 24/7 that can catch as soon as possible when stock is loaded onto a website, when a product page is available, and automatically, with the most minimal delay possible, send that information (The Item Loaded and the corresponding link) to to my discord channel. I would also love for it to be configurable so that I am able to add in additional sites. I would also love to be able to filter what gets shown on the Discord Channel (keywords possibly) as I don't want to get spammed with an obnoxious amount of information from stock loading on the 50+ websites I would like to track. This information is very pertinent to users that resell sneakers and they need the most up-to-date information about a site loading stock on the backend that is available on the front end, or just having an early link to purchase from before everyone else. I have example of such accounts if you are interested, you can respond to this job and you may see what I mean. This information is also super useful when a site is sold out and products restock a few hours or even days/weeks later. Users with this information usually are able to purchase without the public knowing about the restock. I prefer it to be in Python as I can maintain and configure myself. I'm not sure on the going rate for this type of project, so I just put a number that I thought was fair for payment. We can talk more about that once details are laid out! Appreciate you taking a look
