Continue to look for a job before coming but ...

i came over under my wifes sponsorship (Canadian) originally. If he comes under visa, then he has to leave the country and renew from time to time. If you sponsor him, this may improve your benefits from you employer as well.

If there is no job before arrival, at least he has legal status here.

Continue to look for work once you get here. There are companies that will do local hires (for less money, granted) but if he gets one of those, he can stay under your sponsorship. I did that for a couple of years.

If he finds a job where he needs to transfer sponsorship, do it then. All you have to do as his wife is write a no objection certificate. But make sure that you bring along original educational certificates cause they will want that. There will be some other paperwork to do as well, but you can figure that out when you the sponsorhip possibility exists and get the paperwork done here through your embassy.
