Work / Job opportunities for experienced US Civil Engineer in Poland - any hope? [30]

I have the same problem. I live in Poland since the beginning of February, I'm from Holland, I'm a building engineer (degree Bachelor of Science) and 12 years of experience as Civil Engineer at one of the biggest companies in Holland, but it's is not worth much in Poland.

Language is not the biggest problem, job interviews were at companies where the people at the engineering department had to speak English.
They always ask if I have Polish certificates, which i don't have. And the folowing question is how I will solve that problem?

I'm now more focused on jobs which don't require Polish certificates, but no succes so far.
I also look at jobs in the IT-sector.
