Add a banner at the top of a existing joomla site - repost

Hello, I want to add a certain banner at the top of a existing joomla site. Joomla version: Joomla! 1.0.8 Stable [ Sunshade ] 26-Feb-2006 Template: AkoBrightPortal The fixed graphics banner in JPG format will be delivered, it's your job to integrate it. I add two files to this offer, one is the template and one is the screenshot where you can see, how the banner should be placed. AT FIRST: Please can you tell me if this is possible and how much are the estimated costs? Thanks in advance! Best regards
