In our case we have a home based business. Our shop is three hundred and fifty feet off of the road while our house is next to the road. Local bylaws restrict the size of our sign to four feet square. So how do we market effectively? It's simple.
We did an award winning 3D sign that was as big as we were allowed of course.
Does it work? I KNOW it does. We are currently booked into 2016. To suppress the daily stream of looky-loos onto the property we are installing an electronically controlled gate. A (dimensional of course) sign will offer a phone number to make an appointment if they want to come back.
