Front bumper and wing help

Ok i'm not sure who remembers but some idiot smacked my car one when it was parked up outside mine. Any way, I want to replace the bumper and drivers side front wing. Is this easy enough to do? It's a burgundy red k11 1996 micra :) Would it be likely I could get these parts in the scrap yard? How much would it cost me roughly?
