Belastingadviseur gezocht (Engels) voor herstellen inkomstenbelasting 2013

Toelichting:
Hello,
I am looking for an accountant to help me review my tax declaration of 2013. I received a letter from the Belastingdienst requesting a payment related to that year. They claim I did not declare my intention to live in the country and the taxes where calculated on a different fashion (cheaper rate). I submitted the payment and they told me that if I want, I can submit again my declaration for 2013, to get the money back. I would like to know the price for the service and the time required to your office to perform it.

Thanks in advance for your time.
Best Regards
