We used Nandika, recommended on another forum, he was excellent.
There were four of us so I wanted a van. These are hard to get in high season due to some government embargo on imports or the like. A van has to come with a driver too, but Nandika can do your tour in his car if need be.
Bear in mind that if you get a price for hotels that you want to stay in from Nandika/other guide the. if guide books it, he gets ‘drivers accomodation’. If you book everything, guide/driver normally have to pay.
