Having read your added comments I would caution you that "tacking" or leaving the subpoena with another person might well be adequate service. Never fail to show for a hearing without consulting an attorney. Ducking a subpoena rarely works out for the best. Failing to show up can be a disaster.
We do not have a client/attorney relationship until you make an appointment, we discuss your case face to face, I accept a retainer, and we explictly agree to enter into representation.
