need a search module for the zoo component (joomla)

I have a site that have a directory for all the states (50). It has about 25 different categories. So I want people to be able to search listings by State, cities. Also they have to be able to enter one or more categories. So it will a drop box with all the states, to choose their state, a drop box show with all the cities. Then they can choose a categories in the 25 categories. I want the categories to be listed so we can see themwith a checkbox.
