Question : Would it be easier to process my relocation myself of would I need a professional relocation company to set up my move to the Netherlands?

You could process your relocation yourself, but this would cost much time and would probably cause a stressy period. If you want to start your life in the Netherlands well, you can better employ a professional relocation company, as they know the procedures and practices well and can streamline your relocation to an efficient and more relaxed process.
