Alter Template in Magento

We would like some minor changes made to the template of our site [login to view URL] Specifically, we would like the ability to upload content in 3 new areas: 1) A box immediately to the right of our logo in the banner of the site. 2) A box immediately under the search bar and login links in the banner of the site. 3) An area above the Contact Us form where we can input our address info, etc. The content will be provided once the areas have been created.
