Create "14 Day Free Trial" from Game File

I need a to have an existing game file, which is currently available for purchase and download, made into a "14 Day Free Trial" game file. I want to be a able to take the "14 Day Free Trail" version and promote on my website and be able to load onto cd to distribute. This project only requires the winner to take my current game file and create a "14 Day Free Trial" game file. Bids should be between $10 and $40. Quick turn around is needed.
