Well, Vignette, MS CMS and all the really BIG solutions are basically packages that doesnt run out of the box. They are more of gigantic toolboxes that run on one or more servers, priced by CPU that gives you lot's of shortcuts in setting up and customizing a large CMS.
Prices, well, let's just say that they can start at $50 000 and just go up, fast! I'm subscribing to a mailinglist on the CMS-theme, and figures that are mentioned with these systems are $250 000 -> $500 000 once it's developed and ready to run.
Based on the info you gave I'd take a wild guess and say that this might be a wee bit expensive.
If you want something simpler but based on a commercial product you could take a look here at http://www.roxen.com/ they offer a personal edition in the download section that more or less runs out of the box (webserver and everything is included).
This basic version is based on java/jsp and a database, should need arise you can expand it to the full-fledged XML/XSLT version that holds everything in it's own CVS.
This does require quite a lot of XML/XSL knowledge to create all the user interfaces though, plus it costs. Somewhere in the neighbourhood of $15-20 000, at least last year. Setting up the templates for it can be a bit of a b*tch since everything is hacked up HTML in proprty-files (at least the version I worked on), but it's pretty flexible once you are done.
And no, I don't work for them, however I've had a developers course on it appr a year back at my last job.
If you want to go the M$ way, you can take a look at http://www.episerver.com/ (click upper right corner for english version). It' might be MS all the way, but it's well designed, lot's of caching for fast access, quite easy to customize and a really, really sweet admin-interface with all kinds of rolebased permissionlevels, page-templates wysiwyg, formgenerators and much more. And it's priced around $7-8000.
Contact them to see if you can get an eval-version, I think you can, but you need to bind it to a fixed IP. If you don't hate MS, this is a really nice setup.
