Auto Costing Program For Tours Around Sri Lanka, Kilometres & Hotel Costs

There are only about 30 places of interest in Sri Lanka for tourists. I need an auto costing program which will instantly calculate the kilometres, time and cost between these places, which make up a round trip. Then, I need to input about 5 hotel rates at each place, so that the hotel cost can also be included in the output. Finally, I need to enter the sightseeing entrance fees, so that that also can be included in the total tour cost. This can either be done as a stand alone software installed on my computer, or on a website.
