I am interested in doing a project that allows me to provided comparison shopping for specific items. the site should be able to have the same functionality as [url removed, login to view] or www.pricegrabber.com.
Note that i would like the site to be able to crawl the web for products requested by the user. At the same time subscribers to my site must be able to upload their data so that the search engine can pull up their info.
It should be able to allow me to charge the subscribers for rankings and #1 product listings. Again. the sites referenced are good guides as to what i am looking for.
