Cheapest way to fix collision damage?

Got into a little wreck last month. Currently I'm saving to fix the damage. I need a front and back bumper, right fender and a windshield. Where is the best place to find parts? A junkyard would be cool, but I have no idea how to take off the parts. Are there any websites that sell refurbished parts? I've been looking all around cant find anything. The less money I have to save the better. I'm just fixing it up so I can sell it.
