316500 Basic Custom CMS

Hey Im looking to get a basic custom CMS made up, I want it to work similar to wordpress but obviously not as many features as what they have. Here are some of the requirements that are a must. 1: Must be able to add/edit/delete posts/pages/categories from the admin area (wysigyg) editor? 1a: must be able to edit/add/delete navigation links from the admin area 2: must be able to change the templates easily, similar to word press, upload and activate. Or made very easy to integrate the template into the script. 3: must include install files so that we can upload and install the cms for clients, and create usernames for them to access the CMS admin area. 4: there will be several things that will display on the home page ( i will include a template that shows when you first install the cms.) We will be building custom templates around the CMS later. 4a: Must show a side navigation 4b: must show “recent news” last added article from the admin area 4c: Search engine friendly urls (wordpress uses ?pageID=1) for example, ours will use page title 4d: people visiting the web site, or current users on the web site. Stats to show on home page. 4e: a gallery of some kind that can be edited from the admin area to upload images. Gallery thumbnails will be shown on the home page, and when clicked go to the main gallery. 4f: A section for sponsors and friends 4g: a tag cloud that can be edited from the admin area 4h: a contact us form included with the install automatically. Admin area requirements: 1: template admin area 2: able to edit/add users 3: able to edit all text content on the web site 4: everything above. Anything else you guys think would be a bonus to have on a CMS I am basically looking for a basic CMS that you can download or create anywhere, with the features listed above. If you can do this please pm me, there is no immediate rush for the job as i would like it to be perfect. Thanks
