cost of living in hyderabad?

desichap

Hi Friends,
I read few threads on this site and I felt like I will get more accurate answer to my questiosn here so please help me.
I am planning to re-locating to Hyderabad soon (I am currently in USA) and will appreciate your input on figuring out the cost of living in hyderabad.
I have a wife and 2 kids in family(1 is just 3 months old and other one is 5 yr.)
To me, I think the biggest expenses would be rent and kid's school.
How much can I expect to pay for rent for 2-3 BHK apartment in good area like jubilee hills/banjara hills ?
What are other good area near Hi-Tec city?
Also, what schools in Hyderabad are good ones? Normally, how much do they charge per month? Are they private schools or public schools run by central education board ?

Thanks
