Dear Clothespeg,
Sadly to tell you the truth, I have no contact information of any german-speaking resident (attorney) located in Izmir, on the contrary to the issue I'm sure there must be due to the fact that NATO has been a significant and regular headquarters which comprises of german-speaking residents, nevertheless, there must be a minority with an advantage who may handle to meet your demands.

I'll check whether or not i can find some useful telephone numbers for you to get in touch with the authorities of the Izmir Bar Assoc.
