I had a customer call with a reasonable request- now, how do I solve the problem?

In this warehouse, out in the middle of the floor, they have a desk and file cabinet. The power that they need here, and the time clock that they use, rely upon a 1/2" piece of EMT dropped down from the ceiling. Receptacles are set in 4-square boxes on the EMT. The entire thing is supported by zip-ties to an air line.
The customer's request: could I do it a little better?

The roof truss above looks to be 20-25 ft. up. Four Squares poking out from the EMT just seem to beg to get bumped into.
Conventional power poles seem to be out of the question, because 1_ they aren't tall enough. 2) they really aren't supported that well anyway, and 3) the receptacles are in the wrong places.

How would drop power to this location? Oh- I forgot to mention- I also ned to mount a speaker/horn about ten feet up.
