I think what your going to want is something similar to what an auctioneer would use. If you ever go to an auction these days you will seet that they are most likely useing a two speaker system with a wireless mic. Also the speakers are elevated for better range. This is the kind of thing that for good quality and the range your looking at it may not come cheap. Your looking to broadcase 60 to 80 feet.
Best Buy carries PA Systems that should suit y your needs.
The Gemini ES system may be a good place to start.
