Yes you can do both yourself and safe over $200 in shop time. Go to the search ( top right ) and punch in replace headlight. Lots of great threads with pics here.
You can do it on the ground without taking the wheel off and without taking the bumper off like some have done.
Just turn the wheels and go through the wheel well, only release the half side of the bumper you're light is out on. look at all the pics in the threads first and after that you're first time will probably take you 1-2 hours.
