Unfortunately that finish isn't cheap, however you can always offset the cost a little by selling your current finish. You can either buy the pieces separately or contact someone like Roveractive for a full kit. Just make sure you get the parts you need and not more or less (i.e. proper shirt know, nav versus CD radio cover, etc.) See here:
