Drupal - Modify My AdSense Code - RUSH PROJECT

Hi it's James Martell here. I am looking to hire someone familiar with Drupal. It's a simple project. I want to change the Google AdSense publisher ID from the existing one (pub-0619416943796211) to a new one (ca-pub-6289511921621442). I have an existing Drupal module installed that inserts this into the page, but I don't know how it works. I am also hoping to set-up a tracking channel for each of the ads. I would like to award this project this evening if possible. James
