Starting A Property Management Company In Illinois

I'm doing a house hack as well as managing  units for family and I'd like to start a property management company. I passed my IL broker exam and need to get a 45-day sponsor card to the IDFPR. I'm having a hard time finding concrete info on what I need to do to start a company. Do I have to be a managing broker myself? If not, do I need to hang my license under a broker who does property management? Can I hang my license at a discount broker, pay their monthly fee or whatever, and start a property management business for myself?
