Coding - application to scrape eBay sales history data

Hi, I need an app / modification to an existing app that takes user inputted search terms and scrapes sales data from eBay for the returned search results. I already have an application that takes CSV files and uses them to search price information, which can be used as a starting point for this project if desired. The existing app so far does the following - - user inputs a product list (for example EAN numbers or keywords) as CSV - user adds search modifiers as URL format (for example LH_ItemCondition and LH_PrefLoc) - app scrapes data for all products using the given keyword and search modifier input An example URL would be - [login to view URL] Where the input was the product barcode 5055002557224 (imported from CSV) plus the search modifiers for 'buy it now', 'new', 'UK only' The app then scrapes data such as high/low/average price, number of listings What I need: The app needs to follow through to the item pages, for example - [login to view URL] being the top search result. I then need the sales information (in this instance, 10 available, 29 sold) Some listings will not display a number sold and/or available, in instances where only one item is available or there have been no sales, for example - [login to view URL] If this is the case, the app needs to return 1 for available and 0 for sold Information for the top search result will be acceptable but ideally I'd like to be able to obtain data for the top few listings (with data for each item outputted separately rather than aggregated) or specify the number of listings to scrape. I am posting this up to see if I can get it completed quicker than my previously used programmer is able to take on the project currently I can obtain existing source code if desired many thanks, Mike
