i think you should try your local shop at first and sell complete guitars. I think it shows off the quality better. I dont think people will buy a high end kit that is close to the cost of a complete guitar. They look at the $ not the craftsmanship.
If you get your name out there, then try bigger stores. Also online, get a nice website up, all the bespoke makers seem to have one.
Whereas with a complete instrument, quality is first priority.
Guitar shows too, get some product at one of these... And dont look passed wood working shows either
