Chess openings database

I am looking to create a full index of all chess openings and their variations on my website chesschitchat.com. The database will include moves and detailed information on each line. Data inputters will have an easy to use web interface. Bidders must have a chess grade of a chess assocation of atleast 1300, and should be able to prove their playing ability by playing one short game over the internet. The base price agreed on here will cover the bidder entering 20 openings articles - being opening introductions, variations or sub-variations. A further $10 will be paid for every extra 5 opening articles added to the openings database. To have an idea of the type of information I expect to be added please see the following web-page: [login to view URL] Articles must be of sufficient length, detail and accuracy.
