I believe we all start out as a home-based business. Eventually, you need space or you just want exposure, so you look for a high prime visible location.
I don't think visibility brings in more business, just tire kickers. Your competence is what brings in business.
We kept a very low profile for about 18 years. Our first two locations barely had a postal address. We were tucked far away outta sight. We only wanted people who wanted signs coming by. It paid off for us. After we gained a nice reputation, we took on a place on a main road right outside the city limits. Our town has been a bad location and really only good for getting shot at, so we stayed away from downtown.
Anyway, once we moved into a high visible location, we started getting bigger and bigger jobs.... like two and three times a month instated of one every two or three months.
Next, we bought our own building about 11 years ago and it's once again somewhat tucked away, but we're in an easy access area and it's zoned light industrial/commercial.
That last part is the part I don't understand with most home-based operations. How can you spray paint, paint by hand in volume on a business level and not residential, have trucks deliver, run certain machinery, plus other things needed in a commercial sign shop and still have residential zoning, insurance policies and just plain business capabilities ??
I was always told, should something go wrong and you're not properly covered, that's when you'll find out your agent was giving you lip service.
30 years ago, I was told if I had a problem.... like a fire or someone get sick from fumes, my insurance will suddenly not back me because I didn't have proper insurance and then the city would investigate and tell me I can't run a commercial business out of my home. My argument was that if I had paint or screen inks stocked in my basement or garage, it's no different then the normal home-dweller who has house paint in his home or garage. Nope, not so my friend. You see, commercial has to be held to a different standard than the average Joe who doesn't know a thing about this, but it's considered normal practice for a home owner to have this while a commercial business needs to have explosive-proof rooms, lights and higher insurances because we simply do it for a living.
