Registration and work opportunities as midwife/lactation special ...

I have read through so many of the posting for nurses on this site and am not sure to look for work in Doha or try to do my own thing.
I will be joinging my husband, who is working there and will receive a sponsor visa.
Is anybody in private practice as a nurse in Doha, can I apply for a practice number?
Not sure how to go about registration also, can you register as a nurse with the NHA without a job? What is a experience certificate, that needs to be handed in with the registration?
I am a South AFrican registered nurse/midwife. I have a degree in nursing (B.Soc.Sc - nursing), with 10 years experience, 5 years in the UK in primary health care and 5 years in South AFrica in midwifery. I worked in a combined unit: ante, post natal, ceasar theatre and labourward. I ran our antenatal classes and just received my IBCLC qualification (lactation specialist). I also worked in a well baby clinic. Is there privatised baby clinics. Can I try to open my own babyclinic or do I have to work for a public/private clinic.
The diverse salary structuring is also annoying me. Can you argue for a better salary, or do I accept any offer?

HOpe someone will be able to assist me in what options are available.Thank you
