Craigslist querying script / scraper

I'd like a program/script that does the following: -resides on my host's server (OS linux) -I provide in the script an address (or multiple addresses) of Craigslist searches. For example: [login to view URL];subAreaID=&query=nintendo&catAbbreviation=sss -It makes this query every X minutes (I am able to specify in the script) It then appends the result to a flatfile (CSV). I'd like the following stored in the database for each resulting post: Query Address Date/Time of Query Title Location Date/Time of post Body PostingID Category1 - i.e. "seattle craigslist" Category2 - i.e. "seattle" Category3 - i.e. "for sale / wanted" Category4 - i.e. "video gaming" URL I'll also pay extra for an email notification feature. This would entail the following: -For queries I specify, an email is sent to a specified email addresses, whenever that query comes up with a result -For other queries I specify, an email is sent to a specified email address every Z minutes with the latest results from that query Please specify in your bid if it includes the email feature or not. I am open to revisions to this proposal, if anything seems problematic though. Thanks.
