CMS Package for Website Needed

I have a website which I am currently maintaining myself. I want to hand it off to a friend who has no programming experience at all. I want to implement a basic CMS package so that she can log in and modify the main content section of the website without having to mess with any code. The site has a header div (with navigation), a left static content div, a main content div and a footer div. I would assume that you would use a wysiwyg editor. What I need the page to be able to do: * read the content of the desired page out of a mysql database and display inside the editor. * The page has to look like the live page with the editor integrated and main content showing in the editor and editable. * The user needs as much control over the content as possible color, font etc. * I need the editor to have a preview button which will show what the whole page (including header, footer etc) would look like if they press the submit button. * The user needs to be able to upload images and use in the main content (images selected via an GUI). * The user needs to be able to upload files (ie pdf) and hyperlink these in the main content either by text or an image (again using a GUI). * When the user presses submit all the content is to be submitted to a php form via a **post** and written into the database. You dont need to worry about creating a log in or a full database table. Your delivery can only work off one page and I will expand it to cover multiple pages. You can create your own template page to demo the editor on. Again I will integrate the finished editor into the site. I require **all** code. Any minified or compiled code will be rejected as I wish to review all files. I know that my requirements sound long but I am just reiterating the features that should be on a standard editor. So for experiences programmers this shouldnt be a bit task. If you have any questions please get in contact. Regards John
