71. An agrologist who advertises fees must:(1) establish fixed fees;
(2) specify the nature and extent of the services offered;
(3) indicate whether or not expenses or other disbursements are included in such fees; and
(4) indicate, if appropriate, that an additional amount could be charged in the event that additional services are required.
These explanations and indications must be given in such manner as to reasonably inform persons who have no particular knowledge of agrology.
Such fees must remain in force for a minimum period of 90 days after they were last broadcast or published. Notwithstanding the foregoing, nothing prevents an agrologist from agreeing with a client on fees that are lower than those broadcast or published.
