2000 S10 Blazer Bumper help

How hard is it to remove the front bumper of a 2000 Blazer? Daughter got into a small fender bender and hit someone. The driver side front bumper got pushed in. I see where the flange on the bumper got kinked and the bumper is in about 3-4 inches on the driver side. Was wondering if i could get the bumper off I could straighten out the flange that is made on the bumper and reinstall. How many bolts and what would be involved in removing?

thanks
