Check out www.joomla.org. It's an open-source cms in active development. I started using it about 2 months ago and I have already put up 2 sites. My main site is listed in my signature. For web hosting, I recommend www.midphase.com. They have been fantastic plus you can install the joomla admin from the control panel of your midphase account. Go to the joomla forums and look in the site showcase category - you'll get lots of cool ideas!
