Adding Adsense On Site

Hello, I need my Adsense code added thoughout my site. I just recently purchased this website and it use a markup code from the admin panel. I am not fimilar with this markup code and don't want to mess things up on the site trying it myself. I need someone to add my adsense code throughout the site where it is well incorporated and blends well. This should take an experienced person not long at all to do this and is a very simple job. Please do not reply with high bids since they will be ignored. I need this done today and asap.
