eBay Alert Software

I want some software putting together which 'alerts' you when a certain item (which you input into the software) appears on eBay at a certain Buy-it-now price. For example, an Apple Ipod appears at a price between £50-£60 on a buy-it-now basis. Or an Nintendo Gameboy at a price between £30-£40 on a buy-it now. The software will email you immediately once the item is listed (or will scour the website every couple of minutes, on your desktop, then 'pop up' an alert as soon as your item criteria are hit). The software is to run on eBay UK. ## Deliverables Please contact if you want additional clarification
