Validate Product Links - VERY EASY!!!

I need 9.5 million product links validated. I am going to hire several coders for this task. Coders should bid on 1 million product links. There will be a frameset setup for each coder. The top frame will have several links as follows: Check Later - Some businesses have products that are temporarily unavailable. Click this link if that is the case. Not Valid - Click this link if the frames do not open a details product page. A lot of the time it will say invalid link or take you to the business home page instead of the product details page. Valid - Click this link if it takes you to the product details page. I will have other coders check 1,000 random links to see if coders click the correct links for this project. If a lot of mistakes are made, the coder will be asked to redo the project or forfeit the project to another coder.
