The real issue is if you have someone at the front door/desk/counter/sales area/show room to run interference.
I've always been a firm believer in keeping your shop outta sigh, so you don't get the annoying people who waste your time. The customers which really want work will seek you out and most likely make an appointment. However, as we grew, me personally, I did less and less work and basically ran the shop while employees did the work. If someone came in, the guys just pointed in my direction and I handled it from there. After being in business some 20 years, we got a shop on a major highway with high visibility. It still wasn't very accessible to walk-ins, but the visibility took us into a new level of doing business. On each of three walls we had 6' x 60'
signs with just our name only. This was back in the '90's so our phone rang off the hook and we got a great deal of our quotes, cause I wasn't use to this kinda work. As time went on, I adjusted my quoting. What used to come around once a month or so, was coming once or twice a week. We increased employees and equipment in no time at all. We also had the ability to letter 10 vehicles at one time
inside, while still doing 10' x 40' wall
signs and still plenty of room for just about anything else. One wall alone was converted into a 14' x 48' adjustable sectional easel.
However, the thing was, I ran interference for the entire shop. They kept working and my duty was to schedule, quote and schmooze with potential and already established customers. To this day, I still run interference 95% of the time.
