Man, I didn't even think of this. That's all you'd need for shows and what not. Don't need two turntables and a microphone.
My dad and brother own a live audio company. Dad has 35+ years experience and has worked with Live! Technology. They're always buying/selling gear and always look to hook up schools, churches, etc. Being that my brother went to a trade school and my cousins daughter now goes to Tolles maybe they'd be willing to assist. I'll try to talk to them tomorrow.
Really all you need is 2 power speakers, a couple of stands, and a 4 channel mixer or something. You could run everything from a laptop or even a cell phone.
When I thought DJ I thought professional DJ. Didn't even think just something to play music through and plug in a mic to make announcements and such. Let me shift my direction and see what they recommend.
