CMS website + templates

Hello I would like somebody to either make or suggest a free CMS, where there are nice open source templates. The goal is to able to offer other people websites that I will setup for them and then can show a range of templates which they can chose from and I will upload it for them. They must of course be able to easily update the websites themselves. The best offering I have found so far is: [login to view URL] and Wordpress. I would ideally not want to use Mysql. Let me know your thoughts... Thanks Rakesh
