New med spa

Hello, I just need general guidance on my medspa since my expensive lawyers are trash and don’t know anything. I filed a PLLC and then filed for an EIN. I also had to file for a DBA since the previous owner included that in the asset sale. Can someone else tell me what other paperwork I need to do or guide me to a resource? I don’t know anyone else who owns a medspa. I’m in IL
