When are you going, and how many days? Many hotels have attached cabs.Dec-end and Jan are peak times and rates are hiked up a bit. This time of year should be ok.
Also there is an Essen Travels whose services I use from time to time, will pm you the number if you want
The rates are usually not more than 9-10RS for Indica/Indigo with AC on. Without AC, about 8-9rs. Waiting charge is usually around 100rs/hour.( but they dont like to wait, unless you opt for a travel package thing).
