Narrative:

I was taking a load of skydivers over ZZZ and had a small aircraft miss me by under 500 ft. I was in a left hand climbing turn in the pattern just of runway 070. I contacted rockford app. And after 20 seconds was told there was traffic near me. We have a notam for skydiving over the airport and also he did not use flight following and also did not respond on 122.7. In this area lots of planes take off from ZZZ1 and overfly the field without any communication.
