2006 Ford escape window replacement?

I'm currently working on fixing up I bought at an auction, it's a 2006 ford escape. It's rear window is busted and I was wondering how technical i have to get to replace it. I have never done it before and would prefer to accomplish it myself. Also, typically how expensive are rear windows

We replaced the rear window on our explorer by getting the glass at a junk yard for $50.00. Hubby & a friend installed without experience.
