I am also a "word of Mouth" company in Phoenix AZ.
I am doing OK with this tactic because my customers are always very happy with the products I sell them and the professionalism in the installtion. I dont BS my customers into equipment they dont need and there happy for that.
I have joined the ASBA (Arizona Small Business Assoation) and the BBB and hopfully this will help this year for new clients.
I have also done a few BIGGER custom commercial jobs that plenty of people will see and hopefully wounder what company did the install and want to use us for their own private systems.
