While you might think it's a fairly simple task, the reality is that you're gonna need some fairly husky speakers and a considerable amount of power to drive them. This doesn't even take into account any mixing boards you might want.

You're best bet might be to solicit some opinions from local sound reinforcement rental companies in the area to see what they would recommend. That might give you some idea of what you're up against.
