Transportation services for MCS

My family and I are shifting to Islamabad, still undecided which area we are gonna live in but we are looking at G-15 right now, and I intend to study in MCS which is about 45 minutes away from where we are looking right now. So is there any transportation service, maybe from the school itself or public which covers that distance? Also if there are any areas in Islamabad closer to MCS you may know off which have good family apartments (3 or more bedrooms) please let me know. Thanks
