Something like that can be assembled pretty quickly, the type of piping used isn't that thick so its easy to cut even with a handsaw. Metal brackets screwed into the back of the stand to hold in place, if you know an electrician or maybe they can bend at home depot electric conduit could be used as a hanger as well, thats if its LED's or halides, conduit might be to flimsy for a big t5 fixture.
I went ghetto with my current LED setup, I bought a shelf bracket from home depot 16" or 18" fits about perfect with my tank being about 6" off the wall.
