I'd say do it yourself. When i did mine, i didn't know what i was doing, but my buddy had done them before and just told me what to do basically. I learned a lot by doing it, and saved a ton of money. There really aren't any special tools required to do those things, except maybe a spring compressor, buy you can definitely do it without those. At first I was nervous doing it myself, but after doing the shocks and springs on the first wheel, it was a piece of cake. Save yourself the money, and you'll gain knowledge and experience in the end.
