Google Hot trends Keywords extract for 1 year

Hello , I need a freelancer to write a script to collect all the Google hot trend keywords which are published by google at the following link. [login to view URL] One can get the historic data of the same by clicking on the date function. I need someone to write a script to extract all the keywords for the past 1 year (1st August , 2009 to 1 August 2010) and give this to me in an excel sheet. Work will be done based on escrow setup by me. In case a script is not possible am open to someone making this extraction manually.
