I just wanted to say that a shop owner can never go wrong hiring a shop consultant. Over the years I've had several and I don't regret a single one. My first was in the '80s with Terry Greenhut. (since retired). In the 90's, I had Bob Cooper and Elite. In the early 2000s, I went outside the industry and got marketing, advertising, and job leads from an outside source. In the late 2000s, I used Roy H. Williams, also outside the industry.
For those of you hesitating, sitting on the fence, or otherwise procrastinating, get off your duff and just DO IT!
