How difficult is it to replace 08 Impala front bumper?

Got into a small accident and my front bumper is damaged. Want to know how difficult is it to take the bumper off and put it on myself. Saving me some money in my pocket. Asking can it be done with a ratchet or do I need other kind of tools? Front bumper on a 08 Chevy Impala LS.|||The whole story, my friend, is in Chiltons Auto Repair manual at the library. Just a quick look will tell you all you need to know to decide whether you can do it or if you should go to a shop.
