I have German university Dipl.-Ing. diploma. I have Handwerkskarte after examination of my university diploma (headshake here) by Chamber of Crafts. I have passed TREI exam. And I have few offers for upgrade of electrical system in my house ranging between 25000€ and 40000€. That’s my main motivation, but I will accept other jobs too.
