You're looking at about 350-500 for suspension depending on brand and what you drive. But you'll also save on the install since there's less actual labor. If you know how to turn a wrench you can do it yourself. There are also people here always willing to lend a hand as well. You can have it done in an afternoon.
That would be easy to lift. Just need a jack and jack stands. Otherwise basic hand tools. Look up 4 wheel parts and Quadratec. Most of the lifts have instructions on the website so you can see what is involved before you buy it.
I'll pitch in for Dave's bunch at Northridge4x4. Great guy, great prices, great installers. Out in Silverdale, WA. I have been known to wrench on a few myself. You buy the parts and feed the wrenchers/supervisors, I'll help you install it.
