I'm developing a site for a friend's business. He is designing the front-end and I'm slicing/coding the pages and using the CodeIgniter PHP framework to develop a custom CMS. Thing is I'm having to design the back-end interfaces myself and am hoping to find an existing template, but not having any luck. Does anyone know of an existing back-end template that can easily be adapted for a custom CMS? Something that looks similar to the WordPress admin pages?
