Do you have any advice regarding schools in Barbados?

Hi, My husband was born in Barbados and lived there for 11 years before coming to the UK.  It has been his dream to retire back in Barbados and although he's not of retiring age yet (he is 60) he wants to start the process.  We are planning to go to Barbados in January 2016 for and initial 6 months, then if I like it and can get to grips with life out there, we will make the move.     

I'm concerned about a lot of things and feel that there is too much for me to organize before we depart - I need to source a good school that doesn't cost too much (I've looked at St Gabriels in St Michael) also I need to apply for citizenship if I'm going to try and work eventually, plus I need a place to rent for 6 months' in either St Michael or St George - even Christchurch!  in order to be near to the school as I understand that the traffic would be a big issue over there.

Can anyone suggest schools, rentals and even where to get a good priced car/car hire for 6 months'?

My other things is that I know there is an expat meeting place over in Barbados which I would like to participate in as soon as I get there in order to try and suppress the home sickness.....
