I've moved your post off into a thread of its own in the hope of attracting a bit more attention.
If you hunt around in the forum a bit, you'll see we have lots of inquiries about finding a job in France before one has learned the language. The outlook is not great at the moment, even in something like teaching one of your other languages. (Teaching languages is not a terribly well paid gig in any event.)
You might try checking the local university to see if there might be some jobs that would make use of your languages.
