The only body lift that is offered is a 3" body lift from Performance Accessories. Last time I checked it was about $250, but check their website to see what it's at.
As for installation, grab a buddy and take a weekend off to install it. It will save you a lot of money and you will learn a thing or two when doing it.
Any off road shop around you could do it. Honestly though, they're going to charge you up the ASS for labour. If you have at least a quarter of a brain and access to the Internet I would encourage you to try to tackle it yourself.
Most importantly this ^
I remember reading one thread on here where a guy got quoted $1200 just to install the spindles (parts costing ~$300 extra)
There's plenty of information and walkthroughs on both a body lift and spindle lift right here on FRF. Since you're 2WD, we recommend a spindle lift first over anything. The top selling spindle runs $289 usually.
