Since the beginning of my work life as a web developer i've developed many corporate web sites. In fact i can say that corporate web sites are the largest part of my portfolio. While developing corporate web sites i sometimes create some custom modules on demand beside standart requirements. I build an admin control panel for the client easily control every part of the web site. I use my own admin panel module which can be customized according to project requirements. You can keep your corporate web site always up to date by using the control panel to edit all your web site content. In other words you have a dynamic corporate web site with cms (admin control panel) when the development process is completed.
