Craiglist webscraping script

Hi, I need a simple script to be installed (by myself) on my server to parse the whole craiglist network. Practically I want a web interface (a simple homepage) for the script where I would be able to put multiple search criteria for different items (item 1, item2, item3, etc) and save this research criteria in mysql so they can be recall from the homepage through a query. item1 : e.g. Fender guitar price: e.g. 400 $and below city: Miami item2 : e.g. Samsung Tv price: e.g. 200 $and below city: ALL Now, after installing the script, every time there is an item on the whole craiglist (all cities in the US) that match my criteria (e.g. item1 or item2 etc), I will receive a mail with the URL of the craiglist post. That's it, I am a coder too so don't ask stupid price, please. Thanks
