Great. Event management has a good scope and lot of money involved.
Some of the event management colleges in India you can apply in are: with certification, pgdm courses and even PGD.

Indian School of Media
RIG Institute
Pearl Academy
National Academy of Event Management
Krupanidhi School of Management
GD Goenka University

You will have to give MBA exams like CTA, MAT, XAT, NMAT etc to get into this course for 2 years full time degree.

All the best.
