OK, so I've used PHPLD once, but it's mainly geared towards websites. Is there any directory software that is, or can be modified to be a directory for businesses based on location?
Check this - http://www.regionaldirectory.org/ This is their script! Not sure whether it matches your requirement, but check their submit page - http://www.regionaldirectory.org/regional/submit.php You can select your business and location separately.
You should try www.phpmydirectory.com I'd say is one of the best on the market when it comes to build a business directory
I am also looking for similar script or directory that will allow Wedding Vendors to post their info: (DJ's, Banquets, Cake, Photographers, etc ) And maybe even add Reviews by couples.
I'm looking at www.phpmydirectory.com. I've submitted a contact request to see if they can do this, but it looks very promising.
phpLynx was designed as a business directory script. It does other types of directories equally well but it was originally designed for business directories. The script allows for submission of businesses that do not have a website - without adding any mods or changing the code. It has a review function as well.
Could it be used to be a directory of one specific type of service provider? And instead of having categories, it lists by state/city?
Yes ... for example if you want to have a pizza directory and then list each pizza guy in each state or city ... it can do this! Play with their free demo to get a better idea.
