Pre-Kindergarden in Dhaka

Hi,
we are moving with our 3.5 years' old daughter to Dhaka and looking for pre-kindergarden options. The obvious but also by far most expensive option seems to be the American School. Do you know of any other options; i.e. where our kid would be taught by native English speakers (i.e. with at least a few of the teachers being expats?)? (From the websites it seems to me that Dhaka International School, Canadian & Australian school are just sort of up-market Bangladeshi private schools... How international are they really??? What's the share of expat/ local kids?)

Thanks for sharing where you are sending your kids.
