It bothers me to go into a GC and see all these, for lack of a better word, guitars hanging on the wall and I know they sell them!
Playing is believeing! I've heard more than one case of luthiers offering shipping tryouts for people interested. There's a problem there because most guys I know building are up to their eye balls building now, or they're small just building out of a garage!
A well presented web site is important, but in my opinion a small one.
I think, for the buyer, its pretty scary to commission, what's really, site unseen! I think word of mouth, is much more important, than word of mouse.
There were two asses called the Kip brothers who built tooling for the plastics industry, as much as I had problems with their approach, they did have a excellent philosophy that applies to luthiers as well.
They would say, "take care of quality and profits take care of themselves"!
