I am guessing that you would need someone from North America? Can you be more specific? :-)
+1 might help, though most inspectors will travel as long as your covering the costs and time. Since your posting on this site we might assume that your looking at a reported/claimed concours or unrestored level car.
Type of car (in general) might help also since often people focus on specific years and models
Might be interested in discussing the possibilities.
