Website monitor / stock scraper

I am looking for someone to develop a website monitor and stock scraper that will monitor one specific website in real-time. My goal is to extract product availability data from the website so that I can track the stock and availability of various products. This website monitor must be fast, reliable and accurate so that I can make informed decisions on when I should purchase products. The website monitor should also be constantly updated to make sure that any changes made to the website are taken into account. I'm looking for an experienced developer who has experience in creating similar tools. The monitor must be able to output to a discord channel
