I've been looking for a content management solution for a client and have come across solutions from $0 to $250K and I can't seem to determine which one is the right one. This is for a client's site which will have about about 2000 pages initially and possibly 200,000 pages of content in a year or so. I need some flexibility over layout and the ability to take backups easily. Besides the pages generated have to be search engine friendly which doesn't seem possible when working with some GNU PHP scripts. Could someone guide me? Thanks.
