I'm looking to start up a small construction/home improvement/general contractor type business, handling most of the construction work ourselves but contracting out some specialty work like electrical, etc. How do I become incorporated, licensed and bonded to accept and perform jobs in the state of Illinois? Do I need separate licensing, etc for each township and/or city or is there a way to register with the state to be allowed to bid for jobs in each city and/or township? What are the procedures and costs associated with this?
