Dunesh is a driver. His vehicle, a 4x4 has comfortable space for at least 5 people, due to indian standard (real) seats for 10 people. but they can fit more...
The car belongs to an agency.
I have met him on my own search at the Uttarkashi center parking.
For his age, he is a very save driver and really friendly.
He has a good sense "to handle" foreign travellers. We went together to Gangotri and also stopped for a visit at his family half way.
I would like to recommend him, if you are considering any tour in that region
