I have a scuff on everyone corner of my bumpers -.-
Usually i catch them when im tired or in a rush, it happens mate
pot of filler and some spray paint, easy 
A bucket of filler you mean! That will take some amount of filler
seriously, you could sort that in a Saturday morning for about £30 to £40 tops, it would hardly be noticeable.
back to bare metal, drill lots of tiny holes for bridging compound to grab to ( that will fill most of the dent out ) and finish with filler, primer and a top coat of silver spray paint.
