Joomla template editing

I've made new PSD sketches for the site [login to view URL] and need them implemented in the Joomla template for the site. There is already a Joomla installation on the site, I just want you to - first backup the old template, and then - modify the template and stylesheets and edit some html so that it matches the PSD sketches. ## Deliverables View the PSD and JPG files to see the new look of the site. As you can see, the grey bars headers of the content boxes should be in a green graphics, spacing and styles of paragraphs, headings and links need to be updated, among other things. As you can see on my attached files, the big header graphic is different for the different pages. We want you to make it possible for us to choose header image file for the different pages. Please do understand that you are supposed to modify the stylesheet/template so that *all* of the pages get this new look, although I'm just attaching three PSD and JPG files. When the work is complete, the site should work exactly like before, and have the same content, just some new images.
