adsense code to be added to 3 blogs

We have 3 wordpress blogs and we want adsense code to be added to it so two adsense banners are displayed - one horizontally on the header of blog and one vertical on the right side of the blog. for ad ,location and sizes you can refer to [login to view URL] they have 1 top banner and 2 on the side- that could work for us as well- We will give you cpanel and blog admin access. It should be a very simple work.
