Looking for school and house

Hi,
We are relocating to Bali, my husband work is in Kuta so we wish to find the school for our children near this area. Oldest son is 15 years old, second son is 4 and youngest daughter is 2 years old, please recommend us the international school which school fee is medium as we have to pay school fee for all of them by ourselves (not my husband company pay). I looked up on internet and found the Asian international school, emailed them twice but nobody reply my email, how is the quality of this school?
And also if someone know the house/villa (in compound is good) with 3 or 4 bed rooms, a small garden is fine. Price is around 700-800usd/month (or bit more is fine)? We officially move in at the beginning July 2015.

Last question: in Ho Chi Minh (Vietnam) we have the group "AnphuNeighbours" This mailing group is to share all kinds of valuable information that make life easier in Ho Chi Minh - questions, advice required, events, culture, openings, festivals, concerts, dance, language, yoga, bazaars, selling and buying of 2nd hand items, housing (no agents) and employment for domestic staff,
Do anyone know in Bali also have same mailing group like this?
Much appreciate for your reply.
