Contact all TRTOs directly. They will provide you with:
Cost of training
Discounted hotel accomodations
Local regulatory requirements
Visa requirements, if required
Best way to be informed, and make an educated decision.
Stay with well named reputable TRTOs such as Flight Safety, CAE, Boeing, Higher Power, etc.
You may pay a bit more for a quality operation, but save money in the long run from using shuyster operations.
Also check with your DGCA to ensure they are approved TRTOs as well.
