Looking for a Content Management System (CMS) for a particular website project, please read if you can help!?

I don't have a ready built answer that will do this your way, but looking at some of the freeware selections that are in stable release phase at the URL below may get you what you want. All software at this URL is Open Source Licensed in some recognizable way. This doesn't mean that the software is free for commercial use though, so please check with the copyright holders and read the license. A search for "CMS" should get you a long list, about 1795 related projects I believe. Good hunting.
