Moving to Jakarta

Dear Friends,

I am Rajendra from Mumbai,India. I got a job offer for Jakarta with a remuneration of INR Protected content -, accomodation , transportation and housemaid. I am pure vegetarian.
Can anybody guide me that what is the cost of living there and how much I can save after spending on food and other stuffs. Right now for one year I will be alone there then I am planning to bring my family ( wife and two daughters). My wife is a teacher in Mumbai, can she get teaching job in Jakarta.

Please help me to solve all my queries.

Thanks,
Rajendra
