Seeking accounting advice on working in Poland (Warsaw)

Hello,

I am a Polish and American citizen who came back to Poland after living in the US for 25 years. I have an opportunity to work, but would prefer to bill for my services under my American name and still pay taxes in the US so I keep contributing to my social security there. I am seeking an accountant who is versed in such matters and could advise me accordingly what the best course of action would be. Is there anybody you can recommend, or are any of you in similar situation?
Thank you kindly for any information you can provide.
Ivona
