Your task seems somewhat simple from the surface, however your idea of screen scraping does not seem viable, rss is always the way to go in scenarios like this. RSS news feeds are generally as up-to-date as the site.
In regards to making this work for you, I'd be pleased to help you out, ideally you'd set up some sort of shell script that checks the site periodically or on load and then saves the data directly into a mysql database.
Let me know if what I'm proposing sounds good for you.
PS I'm your ideal candidate because English is my native language and secondly I've got the business know how and experience to accomplish what you require with a minimum of instruction.
