How does one go about finding a good pedorthotist?

I've just had bad luck in the past and I know it's because where I live, anyone who deals with feet does nothing but cut toenails for obese diabetics. An athlete's foot (ha, ha) is completely foreign to them.

I'm not thrilled with the idea of having to travel 75+ miles one way for however many trips it takes. (How many trips should I expect it to take?) But if I can get a really good pair of orthotics I'll consider it worth it.
