Content Management Software

I need someone to help me find a content management system that meets my requirements and then to install it. I will also need some guidance or documentation on how to use it. When the solution is identified, I will have you install it on 3 different domains. I would like a CMS that: - is easy to use - has RSS capabilities - preferrably open source like php/mysql (but not required) * It's also very important that it is search engine friendly. I desire features like: - Search Engine Friendly URL's - Individualized Title and Meta Tags - structured directories and navigation elements I prefer something that has a community so that I can purchase add-ons and get support. I look forward to your suggestion! ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
