To have that repainted corrected you're looking at 400-600 bucks.
-They have to completely remove the bumper
-They have to tint the paint to match your color with test panels
-They have to spend a little time smoothing out those scratches and prepping the bumper for paint.
-They have to spray the bumper and clear it....and then probably come back over and wet stand it to try and match the factory orange peel in your quarter panels..

After all that, it still may not be as perfect of a match as it was before and silver is such a hard color to match that it's almost certainly going to seem off in some lighting.
