Since it's featuring nighttime displays, I'd suggest a small, portable, box, anchored into the ground. The street side has a "Return tonight to see this year's winner," while the side facing the house projects a simple "This year's #1 HOA Winner!" powered by a 12vdc car battery and, if needed, a power converter. Basic, simple, elegant, and understated. 🙂 Reusable, portable, cheap.
