Law / U.S. Citizen Moving to Poland - opening business? [36]

I am single, 28 years old, certified lawn care technician, I have 8 year experience. I am currently taking Polish language classes, level wise I would say that I am a beginner. I do plan on starting a business in Poland, not sure if lawn care would be my business of choice there. My business isn't really that big I have a fleet of 34 men and I try to average out at least $10 million a year (including snow removal). I did find a house in Boleslawiec for $500,000 USD I plan on putting cash down. And the real reason why I do want to live there is because it is my home country I might of not been born there but the connection to the mother land is still alive and well as it is in my father and grandfather. The reason of my families immigration to America is because of Nazi control and my great grandfather fled in fear of his life that the Nazi's might find out about his "secret", really he had a gay lover and he knew if he'd stay he would be killed or sent to a concentration camp.
