"Lumenarc" Reflectors...

[om6acw]

At the end its going to cost you same, maybe more, depends of how you are handy, just count reflective material (95% and more is pretty expensive 24x24" it's around $57) bulb socket, cables, rivets , tools if you dont have it you have to buy or rent + your time for fabrication, looking for material. If you stay in work for couple extra hours you can buy them, original with proper used material, each one exactly same..... so I dont think this is worth that much effort....
