7 seater rental in HK

Does anyone know of a company or driver that I can rent a 7-seater car from in HK? I am flexible about renting it for the or just as to and for from a destination. I know that we can get two taxis but with the age range in the group varying from 5 to 78, just want a simpler option that can be planned in advance. Any information will be sincerely appreciated
