I just did sound for a high school graduation (it's the school where I'm a teacher/administrator). It was in a tent, because the gymatorium where we usually have it was damaged in the October earthquake. There were easily over 500 people there, inside and outside the tent.
I managed to cover the entire area with two JBL eon speakers, and one small Eon for a stage monitor. I got lots of complements about how every word could be understood.
So, it can definitely be done simply.Just make sure the hf horns are above the heads of the crowd. As far as the deadness of the acoustic, you might consider a reverb unit, or a mixer with a reverb unit installed.
Good luck on your gig.
