They sell those cheap incandescent shop lights for about $7.00.  You can find
ones that have a nice aluminum parabolic reflector.  Ditch the light and
fixture, replace it with MH, and voila for 7 bucks you have your reflector.

BTW for 250 Watt MH ballast check out Grainger, they have them starting at less
then a hundred bucks, and they also carry the MH bulbs and sockets.
