Hi there Will,
Did you end up becoming a NearbyNow customer? Just curious.
I am a customer and I think they do have a winning business idea. That said, I have found their systems to be a bit problematic and their help files to be weak. In addition, they just recently made a key feature only available for a daftly named "SEO Pro Master" plan; I am predicting a future SEO Pro Master Guru plan ;-). This was a feature I relied on in the SEO Pro plan to allow my clients to update their questions to make them more relevant to their businesses and change verbiage to say "patient" versus "client" or "customer". These may be irrelevant issues to your application - but I thought you and anyone else seeing this thread would like to know.
Cheers,
Ross
