Here are some bands in the Valley you might contact to see who does their kilt repair work.

Mesa Caledonia http://www.mcpb.org/

Phoenix Scottish http://phoenixscottish.tripod.com/

Glendale Police http://www.glendaleaz.com/police/pipesanddrums.cfm

Tempe Police http://www.tempe.gov/policevolunteer...ngops-band.htm

Don't know if it'll turn up someone, but it can't hurt to ask.
