Input: So here's the context.

Our high school's Junior Student Council (JSC) came to me asking if I'd like to help them set up our school's 3rd prom night. Having the equipment (i.e speakers, mixer, cables, etc..), I said sure, but for a price.
 
JSC agreed to put the rate of $9.51/hr (PHP500/hr)  for my equipment and I threw in free service into the deal in their proposal (as they're the ones assigned to make the event happen this year).
 I also explained that they were paying for 1/55th of what the equipment  orignally cost (basically $2091.15+ or PHP110,000+) 

1 week later, I hear back from them.
Apparently, the school admins rejected the offer, saying that I "should be willing to do it for free".


AITA?

I‘d like some advice or insight on this as I‘m still relatively confused on what I should be doing/saying.
