I might be interested, but it would depend on what is required, maybe some more details would be nice.
Is it for the total duration of IFA? Is it only to help putting op a stand (and maybe at the end of the day some cleaning etc) and afterwards you're free to go?
Best option would be a German Pimax user off course, which I am not, and would have to travel about 800km to get there, book sleeping accommodations, etc. though I speak (some basic) German (and French, Dutch and off course English).
