Need Certified Rotax Mechanic to do Prebuy near Portland, OR

I am looking at a Kitfox near Portland, OR and I want to get a pre-buy inspection done on it that is certified in working on Rotax.  I was wondering if there is a list or someone might know someone up in that area that you could recommend me to?  I've talked to some local companies, but no one wants to touch a Rotax.  It has a 912 ULS.  Let me know please 928-403-2030
