I am interested in a program which will amalgamate data from eBay completed listings into an excel spreadsheet for data mining.
The program will need to take search criteria from the user. This will include search term, date range, minimum / maximum price. This interface should be a simple GUI.
The program must interface with eBay, either through a developer API or parsing the "completed listings" page.
The program should provide an extract of data with auction ID, auction completion date/time, completed pricing, seller information, etc into an excel file. This excel file will be a constant, so the program will need to append data to it without overwriting data already existing in the file.
Successful bidder will have previously worked with programs similar to this, preferably with eBay interfaces. Bidder must provide at least one example of a project similar to this.
Timeframe is short - I would like to have this project wrapped up within 1 week after beginning.
