In counties having fewer than 1,000,000 inhabitants, the county board may contract, with advice and consent of the sheriff in the county in which the request for contract services is made, based upon a determination of law enforcement needs of the area in which contract services are sought, with one or more incorporated municipalities lying wholly or partly within the county to furnish police protection in the area of the county that is not within the incorporated area of any municipality having a regular police department.
