I would appreciate any of you knowledgeable about bumper fixing to give me
an estimate as to what you think it might cost to fix the front (with more
severe scraping) and back (flexed damage) bumpers.  That way I know what to
expect from a body shop, and whether I have to wince.  For reference, I am
in the Sacramento CA area, but what they do in your locale is good enough
for me.

I know that a DIYer can buy paint and sand it and get it working, but
perhaps it will be better if the pros do it.  

I am footing all costs on this, so it's not as if insurance is behind this

Also, do all body fix shops charge for estimates like these?

I think I did a good job of getting a wide-angle and macro'd view.
