Design a template for my photo gallery

We have a photo gallery using the open source package coppermine. [login to view URL] This package has the concept of templates to change the overall look and feel. We want a new template designed to make it more user friendly and nicer to use. This will involve editing an existing logo to fit, and then creating graphic buttons, etc. There is information on the site showing how templates are generated. You will need a good knowledge of html and php, and ideally knowledge of the package itself. Also, because the site we are running is live, you will have to download the package, and install it on your machine, and get the template working on that, and then once it's all complete install it on our live site.
