Need accountant for backdated zero-financial statements (Sp. z o.o.)

Hello, ​I am looking for an independent accountant to help me clean up and update my Polish Sp. z o.o. company (APFEL SERVICES SP. Z O.O., KRS: 0000866481, NIP: 5272939828) so I can activate it and open a corporate bank account. ​The issue: Financial statements (sprawozdania finansowe) and CIT-8 tax returns have not been filed for the last 5 years, but the company had zero activity and zero income during this period. ​My goal: I want to prepare and file all the backdated zero-financial statements and tax returns to bring the company into full compliance. ​Please let me know your estimated flat fee/price for the whole package. ​Thank you
