Cost is relative to what needs to be done.
Read and study some more before you go, lots of info here.
Cornerbalance is done in conjunction with alignment and adjusting ride height.
Before anything, all components like shocks, struts, balljoints, tierods, bushings etc. need to be checked and replaced if necessary.
Most likely, the main bushings in the trailing arms (Springplates) need to be installed and you may want the bump-steer kit (Spacers under the rack)
You have to decide on ride height; what setting do you want?
Next is alignment:
Alignment shops have the factory settings in their computer, which most people don't want.
What Camber and Toe do you want on the 4 wheels?

Defective components will show up during alignment and a good shop will tell you what needs to be replaced. (Which adds to the cost)

Study some more; do a search here. It's been covered many times.
