Hanging mirror and shelves in the apartment

Hello, i am looking for a handyman that will help me with hanging my mirror, 2 shelves and 1 coat hanger in my apartment. i do not have a driller, so i can't do it by myself. With shelves the issue will be super easy, the wall is made of plasterboard and i have all screws and dowels for that. There might be some difficulties with hanging mirror and coat hanger in the hall way as - according to my landlord - the walls are made of stone and it is difficult to hang anything. i also do not have any screws and dowels for that.
