Where can I be initiated into Tantra/Kalachakra in India or Tibet?

I recently read an introductory book on Tibetan Buddhism and am intrigued by Tantra & Kalachakra practice. I have been practicing meditation for the last 2-3 years, but not under the guidance of a guru. After struggling for 2-3 years, I have finally realized the need of a guru so that I can start practicing seriously. Next year, I have a 3-month vacation and I'm thinking about going to a monastery in India/Tibet (I live in India) where I can be initiated into tantric practice. **What are some places in India and Tibet where Tantra/Kalachakra initiation is possible?**
