To get your private helicopter license you'll need to get some training and practice in flying the helicopter which can cost from $10,000.00 to $15,000.00 just for the lessons and helicopter rental.
For training to fly a helicopter it takes around $30.00 to $40.00 per hour and then the cost of the pilots license which I'm not sure of the cost for the license itself because I never flew a plane but it's expensive just to get the training.
