A few yrs ago I bought a software program from Quentin Brown that allowed me to create my own "mobil templates". I think a guy named Will R (Will Reilly) on Warrior Forum sells a program for making Mobile Directories.
My "template" is based on one I came across some time ago (see photo below)
Again what I like about Mobil Directories is that I don't have to depend on any participant's choices.....they either take MY choice or they're not participating.
And....when they see a competitor IN the Directory.....they MUST take a spot also.

You could also take a look at a Demo Directory I set up for Restaurants.....
