Craigslist and eBay search and compare website

I'd like to build a software program that searches craigslist, takes key words from the listing title, and searches for these keywords in completed listings on eBay. A summary page would return those craigslist items whose asking price is substantially less than the average of completed listings price on eBay- or just all craigslist items with the craigslist asking price and eBay completed listing average price listed next to each other for comparison . The program would automatically run the search periodically (say every hour) comparing recently posted items.
