A person who operates a tour company is a broker. A broker is a middleman. Brokers buy or arrange items or services and sells these items or services to the end buyer. Some examples of brokers are:

Independent insurance agents. These agents do not provide insurance; they arrange insurance for you from an insurance company. Insurance agents usually get a commission from an insurance company.

Stock brokers. Like insurance agents, stock brokers help you buy and sell stock. They don't own the stock. These brokers also receive a commission based on the amount sold.
