AdSense Link decoder

Hi, looking for someone to create the following script. Google AdSense is placed on a website. The dynamic link of one of the adsense text links (opened when visitor clicks on an ad) must be retrieved after the ad has been loaded AND must be useable within the client, to eg. - not intended use - load the ad seperately automatically. Should be done in JavaScript. Please post your bids. Full amount will be put into escrow and released after completion.
