Comparison shopping

I want a simple program written which reads in UPC numbers of a product from a text file, then does a search on the following sites: [login to view URL] (selects lowest buy now for shipping+product) [login to view URL] (selects lowest buy now for shipping+product) [login to view URL] (selects the price for the product) [login to view URL] (selects the price for the product) [login to view URL] (selects lowest buy now price shipping+product) [login to view URL] (selects lowest NEW buy now price shipping+product) [login to view URL] (selects lowest buy now price shipping+product) [login to view URL] (selects lowest buy now price shipping+product) It should grab the price, shipping, upc, and site name and write it out to a file in the format below: 'site','upc','price','shipping' The budget for this project is $50 - $100 and I need a quick turn around.
