When may a paralegal solicit clients?

A paralegal may not solicit legal business, either for herself or for an attorney.  This is not to say that freelance paralegals cannot solicit attorney clients; they just cannot solicit non-attorney clients for whom they provide direct legal services.  See Tex. Disciplinary R. Prof. Conduct 7.03 and Canon 5.  See also Texas Penal Code 38.12, Barratry and Solicitation of Professional Employment.
