The commissioner shall create and implement a business hotline program. The program must provide for a telephone number through which the department shall provide, during regular business hours, in-state and out-of-state callers with information regarding how to do business in the state, the services and assistance available to businesses, the advantages of doing business in the state, and information on state and other resources that provide assistance to businesses in the state. In addition to directly providing information, the department may use the business hotline as a clearinghouse through which to refer callers to other federal, state, local, or private sector economic developers. The program must include an in-state and out-of-state marketing campaign in support of the program. The commissioner shall follow up on business leads gained through the program and shall gather data on the results of calls, including business expansion, location, and startup.
