I have a site design in a PSD file. I need a Simple CMS system build around it. The design is [login to view URL] I need a CMS system built so that it is easy to add new events to the event page, Add songs to the song list, upload photos to a photo gallery (I have a script for this) and add and edit info pages. System must have an admin log in and must be made with cross browser compatible CSS. I will be adding a Photos tab to the navigation.
