98 CRV Passenger side Mirror replacement?

Hello,

My wife had the missfourtune of having some nob smash the passenger side mirror in a parking lot. The plastic housing smashed. I was wondering if anyone would know the aproximate replacement cost of the mirror, where I could order the part (in Canada?), and if a non-mechanical retard like myself can change this mirror (it is a power mirror too if this makes a difference).

I am not very mechanical.

Thanks for any and all help.
