In Illinois there is no single statewide "general contractor" license for handymen; most contractor licensing happens at the local (city/county) level, with statewide licensing for certain trades (notably plumbing) and for certain specialty registrations (roofing). In Carterville (Williamson County), you should expect a city business license/contractor registration plus permits for many jobs, and you must not perform work that requires a state-licensed trade (especially plumbing) unless properly licensed.
