Hello Mr Debo Prasad Maharan
Sorry to say.See for 20 seat you can easily make in 15 to 20 lakh with the latest technology and update.
This is not at all related that you would have 1 crore.For 1 crore you can make 100 seater center.We are setting up center in bhubneswar and we can help to any people for this with business.
