KLIA taxi to Cameron Highlands late in the evening

We will arrive at KLIA at 9:25 pm and have to get to Brinchang, Cameron Highlands after clearing immigration and picking up our luggage (so maybe 10:30 pm).

Will it be a problem to find a taxi driver who is willing to go on the long trip this late? I am aware that it is going to be expensive as the driver will have to go back empty. How much will it be approximatly?
