Work / Job opportunities in Poland for a foreigner? (other than a teacher) [175]

If I can speak both Polish and English fluently and without accent on either my polish or english, what types of jobs can I hope to find other than teaching. I was born in Poland but moved to Canada when I was 5 so I have my dual citizenship

My education isn't anything to brag about actually. I never liked school and I got into retail here in Canada. I manage/part own a sporting goods store. I have a good head on my shoulder but that means nothing on a resume.
