Simple Ebay results scraper

I need an Ebay software scraper where I can choose a given Ebay main category and it will start scraping ALL the available auction page listings and drill down to the smallest subcategory possible inside the chosen main category. I will need to be able to enter 1 or more keywords or a sentence into the scraper and the software will then check each auction listing page to see if those keywords or that same sentence is mentioned somewhere on the auction page. When the software has finished scraping it will be necessary that the search results can be sorted, so that the items with the highest price and highest number of sold items are at the top of the list. I also need to be able to individually sort only highest price or highest sold number of items. The last column will list the link to the auction page. The results can then be Exported to csv/excel. The software should work on all Ebay sites. The software can either be 1) A server side script that can be installed and run on a shared hosting linux server 2) Or a Windows OS software that has to be multi-threaded.
