I know this is a question with no "right" answer, but insofar as the question CAN be answered, can anyone please direct me to any of the "best" guitar builders in the world? I wish to commission the construction of two six-string acoustic guitars: one steel-string, and one nylon-string. The guitars need not both be built by the same luthier. If for any reason the luthier(s) suggested do NOT have especial expertise in the installation of multiple state-of-the-art pickups, I would also appreciate any input on qualified artisans for that task as well. I'll pay what it costs, and pending proper vetting of the luthier's work, and submission by the luthier of a legally-binding, written guarantee that the work will be completed within one year, I'll pay half up front. Luthier(s) must be properly bonded. I'll go anywhere that's safe to go, and I will purvey any wood(s) the luthier(s) may be unable to purvey themselves. Thanks.
