Need an editing system for a restaurant menu.

I need an editing system for a restaurant menu. The menu has submenus. Each submenu has menu items. Menu items have: name, price, description and other fields. The system needs to allow the creation of a menu and the adding of submenus and items to that submenu. Also... the system needs to output a text file of a certain format. See the attached file. The work needs to be developed on my server. Ideally I would prefer to use an XML file instead of a database. If using a database, then I would need to have a setup script for it. The job is very easy. I need it done ASAP. Please send a PM for any questions. Thanks. OM
