Coach to rent

We are from singapore and we will take plane going to KL. We are 15 persons. We are looking for a coach or van to rent to pick up us from the airport. . We are planning to go to twin towers and around KL City then visit also the strawberry farm and take the cable car before we proceed to Genting highlands where we gonna stay. So we will be using only our service for 1 day from 9 am to 6 pm. How much is the rental ? Is it covers the diesel and Drivers service? Thank you very much . Some questions to ask later
