Let me suggest, if you're going to attempt to make your own bracket, try to put your idea on a piece of card stock, or poster board or something like that so it has a bit of rigidity but still easy to fold and cut. Cardboard will work, but use a cereal box or something, not a shipping box.

figure out where you want your bends and how you want it shaped, mark your bends and holes in ink, then flatten it out and trace it on a piece of metal (steel, aluminum, stainless, whatever you want) and bend it where you put your marks on the cardboard. Drill your holes, and mount it. Much easier than trying to weld everything together.
