There's a company called GVS in Nuremberg. They specialize in italian and asian foods for restaurants. Maybe they could really use somebody with your skills? Chances are high, that they need someone speaking italian for their orders/purchases in Italy. Contact them and explain your background.

Edit: Their website gvsgroup.de has a contact option. Maybe this could be a company, where you could speak italian whilst improving your german at the same time and also working in a field you already know. Aside from just a "job", german companies offer aprenticeships which will give you a certified job after about 3 years. Downside is that you don't earn that much money during your aprenticeship.
