Corporate trainers salary in India

Finding the corporate trainer in India is very difficult. There is no branded website to get the corporate trainers across Inda. Currently, the company HR is find the corporate trainer from the Job portal (Naukri.com, Shine.com, MonsterIndia.com etc..). But, those websites don't have the option of Corporate trainers.

Also, .NET/C# technology trainers are getting paid between 5k to 15k per day depends on the negotiation.

The mediator company one who provides the opportunity to trainer will earn more than what the trainer is getting. This is absolutely wrong.
