A lot of general mechanic shops can swap out bushings or install stuff. If you want to buy stuff order from tunersports.com and support the forum, the price you see on the site is the price shipped. If you need an alignment West End is the place to go. If im too lazy to do my own alignments i usually tend to go to les schwab.
Me getting quotes of labor costs for getting my suspension parts made me just do it myself because those people wanted like 700-800 to install struts and springs.
You should have an easier time with the coilovers since you just take out the old strut/spring assembly and put in the coilover and viola.
Perk of having mechanic friends: they do side work for cheap.
I think I paid a buddy of mine $200 to install wheel studs in all 4, struts, lowering springs and LCAs (which took way more work than they should have).
