advice on moving to Mumbai

Hi , We are an Irish family looking to move to Mumbai and Wonder If someone could give us some advice on Accommodation , My husband will be working on The Chattrapathi Airport .We have a 13 year old son in year 8 in the British curriculum, hear there are good international schools . What would be a good area / district to live so school & work would be in commutable distance . Does anyone know what the fees are etc., Worried mostly for our son settling and trying to decide if we should move the whole family or not . Would be grateful for some advice .

Thanks
Frances
