To the OP, why not get him some LED tail lights to update the look of the rear? They'd only run about $250 shipped, or in some cases cheaper. I'd really like to know where and how an Mtech bumper could come under $500 painted.
$200 for the bumper (aftermarket, but polyprop), you could always find someone to paint for under $300.
