I have a suggestion for Jimmy...
I totally get what kind of person he is. Very artistic, very very laid back about stuff... maybe even to the point of bothering some potential customers with the way he interacts. To be very honest, I think that personality is part of why he can do as well as he does with the art of building his basses.
IMHO, what he needs is a person to be a "business frontman". Field all the questions, give the kind of specific answers people want to hear, and relate the importance of serving detailed specification requests... maybe even be the shop champion for the customer and do the wood search Jimmy is hesitant to do. Stay on top of emails and maybe even phone calls, etc.
That way, Jimmy could focus totally on just the instrument building, and his customers/prospects would generally have a better experience.
Just a thought. Bottom line, despite my somewhat crotchety responses today relative to my more typical post, I DO want to see Jimmy succeed in a big way. I see what he can do, and I want him to keep doing it, and do it more.
