Moving to Denmark without job (Finance professional)

I am moving to Denmark (copenhagen) with my husband and 7 yr old daughter. Both of us are finance professional (over 10yra of experience).
I hve got a job but husband is still on lookout - keen to find out more on following:
1. how difficult it is find a job there for a foreigner? How much time we shall expect this will take?
2. What shall we expect as monthly expense?
Any suggestions are welcome  Thanks
