The County may contract with any incorporated town or taxing area in the County to provide to the municipality or taxing area goods, services, or construction of the type the County government performs for the County. The contract must specify the particular goods, services, or construction to be provided by the County and the fee to be charged. The fee must not be less than the cost incurred by the County, including a reasonable allowance for overhead costs. Any municipality or taxing area which receives and pays for work is not liable in damages to any person solely on the claim that the work was performed in a negligent or faulty manner and that damages or injury resulted. The County Attorney must, without charge, represent and defend in court, if necessary, any municipality or taxing area in any suit, claim, or demand made against it as a result of work provided under this Section.
