You could try to post here in the Nordic Languages forum first. I don't know how many German speakers there are here, but you'll find out if you post a question.
(We can't translate for you, but help you with specific questions).
If you don't get any answers here in Nordic Languages, you should try the German forum instead. You can't really expect to find any Norwegian speakers there (but there may be somebody), but you can get help with translations to English, and then translate from English to Norwegian yourself.
