Chicago is one of the deepest production markets in the country outside of LA and New York. Crews, studios, and post-production talent are dense, rates are more competitive than the coasts, and the city works as a stand-in for almost any American urban setting. For service businesses (facility management, cleaning, home services, professional services, coaches, and consultants), that means you can hire a full crew locally without a travel premium.
Working with a Chicago-based partner also matters for scheduling: you can visit the studio, review dailies in person, and shoot multiple locations in a single production day.
