My site rehabfinder.info is using the directory plugin

I wanted this page to look symmetrical and professional, to make good use of the space. However, in the categories half the states are missing in my categories, and I was simply thinking of establishing some type of search bar drop down list that would help them find what they're looking for. If this couldn't be done, could I at least get the 3rd category placed next the the first and second and have all my states listed. I'm doing my best to make the best possible use of this space, since right now the page looks scattered and unprofessional the url is http://rehabfinder.info/rehab-directory/
