Hi Ramon --
Michael Elwell, a luthier specializing in classical guitars, is located in De Smet, Idaho, which is about 60 miles from Spokane. I am not personally familiar with his work, but he exhibits at the Handmade Musical Instrument Show held annually just outside of Portland, so perhaps some of our Portland members may have seen his guitars. In addition, Mr. Elwell notes on his website that he participates in the Inland Northwest Luthiers Association, which meets at 6 PM on the first Wednesday of each month at Woodcraft, 212 N. Sullivan Road, Spokane Valley, Washington. Your client might consider contacting Mr. Elwell and meeting him there.
I hope that's of some help.
