News portal CMS (php + mysql)

I need a CMS for using as news portal system. It will act as an online newspaper to end users. Please see the details. ## Deliverables Here is the description of the system; - Users as admins, moderators, editors and subscribers - Editors will submit news articles - Moderators and admins will confirm and publish these articles - Subscribers (optionally any visitors) will be able to comment the articles and other contents with a "bad-word filter" logic. - Admins will have all the operational and technical rights to manage the system And here are the modules / features this CMS should have; - User management - Subscription management - Article management (add, edit, delete, publish, archive) - Archive management - Category management - Picture gallery - Video gallery (.flv) - Newsletter system (using external SMTP server with authentication) - Ad and banner management (start - finish times, enable/disable, location to display etc.) - Internal messaging system - Poll management - External RSS feeds that can be configured easily - Article, page and visitor tracking (number of visits) - User tracking (last login time is enough) Other important points; - Site should be translated (by me) to Turkish easily without changing the codes. I mean, all the interfaces should be written parametric, so that I will only need to edit a few "language files". - The links should be "search engine friendly". I'm planning to use IIS or WAMP on windows server. So "mod_rewrite" and similar native apache/PHP extensions may not be available (I'm not sure) - I will only give a "main logo" and "content articles", "content pictures / videos" etc. So every other visual details (like theme, visual effects, animations etc. ) should be provided by the coder. - I need pure and clean PHP codes which only requires native PHP modules (and maybe Zend framework) - I need a way to hard-code the script to run for only a "single specific domain" before publishing to live site. I don't want it to be stolen on the hosting server. - Top articles and related pictures should be very smooth and bug-free. - I'd like there to be a "last minute news" scrolling horizontally. - Thumbnail images should be created automatically for using in list of articles. Most important thing is the front-page. Normally it should look like an online newspaper. I don't need a clone site but the following link may give you an idea about the front-page; [login to view URL]
