Over in Mazda3 land, we have a local (Richmond) mechanic that can do quality work, cheap.
He works out of a home garage, but is equipped to do a lot of work.
He has installed springs for probably 20+ members of the BCMazda3.com forums and has also installed a few sets of coilovers. Of course he can install most everything else too.
PM me for information if you are interested.
