I was already working before I even get my NI number... Hehe, seems that your husband would like you to work straight away... lol (but there's nothing wrong with that though)...
IMHO: One step at a time Nids:
Rent/Sell your Condo Unit
CFO Seminar + Sticker
Pack your Things
Fly to UK
Enjoy UK for some few weeks/months
Apply for NHS
Apply for NI & Job
Just take it easy... Life is too short to be in a hurry/bitter
