hi friends i want to make yellow pages site like justdial where we can get fee php script for this business directories thanks waiting for you responses.
If you searched google and there isn't any, chances are you might have to do make one on your own or hire a web development firm.
There are many Yellow Pages clone scripts (try searching the scripts directories, eg: http://www.hotscripts.com/search/all-scripts/yellow+pages), but I doubt that you'll find a free one.
