We recently used Bobby Thakur (Kalka Travels) for 12 days travelling from Delhi through Rajasthan. Bobby has a broad range of vehicles available at what we considered to be reasonable pricing.Our experience with Bobby Thakur was great. We had a good driver (Rajiv) who was always courteous, polite, well presented and never 'pushy' although he was always prepared to offer suggestions if we wanted anything in particular. I don't hesitate recommending this company and believe they would meet all your requirements. Their website is http://www.carrentaldelhi.com/. You can email Bobby Thakur through his website and get a quote based on your requirements.
