eBay Pricing Project

I need an application to automatically enter bulk / multiple enquiries on [login to view URL] and return all the results in a text file. I do not know if this is even possible, you would need to establish this. I envisage an application allowing me to enter certain inputs, and I anticipate these to be: - item description, number of days (30, 60 or 90), price range. The outputs will be in the form of a text file with the average price, number of listings, top 10 items (by descending end price - showing item title, sold, end price, bids). I expect the routine will be producing 500-1000 lines per 'run'.
