Commercial production companies are usually made up of at least one Executive Producer, a Production Manager, and several coordinators and sales people to maintain all the moving parts of bidding, pre-production, production, and wrapout.
If you are looking to speak to someone in a decision-making position at a production company, you're better off speaking to the Executive Producer. Their job is to onboard new directors, manage existing rosters, and work with clients, agencies and other stakeholders during all facets of commercial production.
