Looking for someone to take care my tax return and advice: Chiropractor

Toelichting op de werkzaamheden
I am a chiropractor just moved here from Australia. I am working as a sub contractor (self employed/small business), I have my KVK and personal tax number and have already started working.

I am looking for someone to take care of filing my tax return for me, when it needs to be done and general taxation advice, as I have no idea of how the system works here. But I have been told there may be a tax free threshold for starting out here? Would you be able to quote me an estimate price for your services?

I basically have one source of income (an invoice I provide for services) and a small amount of deductions. Nothing I would imagine is complicated. I'm not sure of the legal form of my company.
