What will the cost of this tour package?

My husband & I are flying into Kerala on October, 2015, for a 10 day stay at Munnar on the beach in. We planned on visiting the best places of Munar so obviously we need a rental car for the duration. My friend has recommended me a cochin based cab taxi service.
