re: Able to upload all of our businesses via CSV upload.
This is not a function of the cMap template. That is a function of the CSV Import extension which you already have as part of the Extension Pro Pack.
re: Drop Down menu for easy organization
The drop down is for the category selection for the user. I assume this is what you mean by easy organization?
Yes, cMap is responsive theme friendly.
re: User friendly/easy to use
I personally believe the cMap template is the easiest to use for you because it uses the Template Customizer for configuration. The Template Customizer offers a live preview as you change it options. It basically functions exactly like the theme you are using in WordPress (if it uses the Customizer that is).
I’m processing the exchange right now. You will receive an updated sales confirmation email shortly.
