The demand for mediation shall contain a brief statement of the dispute and the relief sought by the licensee filing the demand.

   (2)   Within 20 days after the date a demand for mediation is served, the parties shall mutually select an independent mediator and meet with that mediator for the purpose of attempting to resolve the dispute.
