Ask on mikrocontroller.net. There will definitely be people who know who in Germany is doing it or maybe even offer to do it for you. One of the last old fashioned forums on the net. German speaking but nowadays that shouldn't be a problem.

Good idea. Haven't thought about mikrocontroller.net, I even have a login there for quite a long time.

Prepare to get yelled at, berated and belittled.
