Please advise; How much can I charge per hour? (Oslo)

Hi all. Planning to move to Oslo soon, busy with the visa process now.
I would like to find our what I can expect to earn there. I am a UK qualified maternity nurse, I do sleep training for babies and children as well as night nursing. There is not really a word for this profession in Norwegian, nor is it a common profession there, so it's hard to look it up. Working through a Uk agency, for a 24hr day, 6 days a week, I can earn anything from £800 to £ Protected content week, living in, food etc supplied. However in South Africa it's a bit different, only working nights, 7pm-7am, charging about NOK100 per hour. Can anyone please suggest what I can expect to earn per hour or per night working in Oslo? I have 5 years experience,certified, and I speak Norwegian. Thanks in advance!
