Here at Big Bee Consultants we do Java. Mostly. We also have a considerable body of experience in website development, including the CSS styling, XHTML & SVG integration and PHP content management systems.

A lot else has been written on this subject so we'll keep this brief. Concrete5 is a relatively new PHP content management system (CMS) with the MIT licence.
