Website Design

I want a website that has a clickable US map. When people go to the site, they can click on their state and then click on their county. Once there, they can click on a category (i.e.-cooking lessons) where they will be shown profiles of instructors in their area that give cooking lessons. I would like to be able to have the instructors post their own profiles and update them. I would possibly like to have a merchant account as well.
