Moving to Namibia - what is the process to have a work visa in Namibia

Good day

I am an Allied Medical professional from South Africa in the process of opening a practice in Windhoek. My mother was born in Namibia but lives in South Africa. Can somebody please advice me on the process of gaining a working visa in Namibia? Does it make it easier for me, because my mother was born in Namibia?

Kind regards

Reon

We have received work permits for 2years for Namibia. What are the practicalities of moving?Cost of going through customs with car×furniture?

What grocery items can we take with us?
