I would like to offer a new template for free. This template has changed admin side too. I don't have my hosting at this time, so I can't show you the demo. Send your request via email and the skin is yours.
I want to change the template of my quick.cart site. I follow this manual:
step 1) copy directory "ablaze" to Quick.Cart "templates/" directory
step 2) log to admin panel and go to "tools" -> "settings" page and select "skin" to ablaze
step 3) after that change script will automatically copy missing .php files from default skin directory, but if there will be some errors (missing files in skins directory) copy missing files manually from templates/default/ directory to new skin
