organize content on joomla site -- 2

Take a good look at the Patient Library menu on the left side - [login to view URL] Roll over all the links to see sub-menus and sub-sub-menus. We would like to come up with a better way to organize this information on our new joomla site. All the content articles are there! We are open to any ideas on how to present the information quickly an clearly rather then using a drop down menu. Need this started immediately! Budget is $90
