I need to devleope a web site that list areas of the country like miami south miami, north miami, etc. it also list attorney, limo services , etc. The web client comes to the site to find, say, a limo service in the north miami area. He clicks on a radio button that selects the area (North Miami) and then selects limo service and clicks go. The site then lists all the limo sevices in North Miami. How do I do that?
