Your budget is a little small. I can only give you the simplest configuration! A pair of single 12~ 15 inch speakers with 250~300 watts, plus a mixer with a power amplifier, a pair of microphones and a pair of speaker brackets are enough! ! Speaker 1500+ Power Amplifier Mixer 1000+ Low-end V-band Microphone 200,+Speaker bracket and wire are almost these!

The above personal views, I hope to help you! !
