Professional CMS?

[ThreeD]

Does anyone here know of a professional CMS that gives you the opportunity to customize the layout 100%? We'll gladly pay a couple of thousand dollars for the CMS if it's that much better from the ones you get for free. (Typo3, Mambo, Joomla etc..) We want to be able to create the website layout exactly the way we want with modules, but we don't want to worry about the backend programming part too much.

Most likely the CMS type CNN, MTV or ESPN are using are custome made, but we're essentially looking for that type of CMS. If we have to have a CMS custom made for us, that's fine as well - any companies you guys know of that can help us design a CMS from scratch or a company that sells excellent fully customizable CMS solutions?

Thanks in advance for any feedback..
