Data Gathering Script for eBay.co.uk Listings

We are looking for a relialbe script that finds new listings on [login to view URL] for mobile phones. The script should be able to grab the phone number and email address from the listing page (if it's there) and add it to our database. eBay is good at letting you break down what you want the search results to include not include and so we want the programme to only visit listings that match this search critera. Payment will be in parts with the largest chuck paid once we see the programme working correctly.
