Dell outlet scanner/grabber

I'm looking for a program that can refresh the Dell Outlet Store and add systems to the cart based on specific criteria such as price and various system configurations like processor type, amount of memory etc. 1) I should be able to select how often the program refreshes the store - like x times in a second, every 5 seconds, every 10 seconds, every 5 minute etc 2) The program should be able to scan and add systems on the cart based on multiple options including - price range - The system model names ( Latitude, Studio, Alienware etc ) - Processor name, Graphics card name, Hard drive size, amount of RAM/Memory etc 3) Ability to add to the cart multiple matching systems from the same page. 4) Ability to scan and order from both Dell Home outlet and Dell Small Business Outlet store.  5) Automatic captcha verification and auto filler/entry. ( This is required before the system is added to the cart ) The program would be run on Mac OS. If an other OS is required, please let me know!
