Any person other than a member of the Bar who acts as intermediary between a third person and an advocate shall be presumed to usurp the functions of an advocate within the meaning of section 133, who:(a) makes or promises or causes to be made or promised to a third person any reduction in the charges of such advocate, or
(b) persuades an advocate to forego any part of his charges, or
(c) procures, promises or agrees to procure for such third person professional services, without any liability on his part towards the advocate for his charges or,
