Happy to see your post about starting an english school. I prefer India is the right place to start english school and making profit. Here parents are willing to pay money for their child education as they are giving more priority. Also, india is the very potential country to start a business and making profit as india have more population.
I am running two schools here and you can make profit without any doubt. If you need detailed report, i can help like how you can make a profit based on your investment. Thank you!
