Lowering My driveway dropped kerb any idea of how much it would cost?

Hi i’d like to know if there’s any of you here have any idea of what are the process and the amount of construction for lowering the dropped kerb infront of our garage. Our house is beside the main road and im having a hard time every time I park my car. I already went to the city hall and told us to get our own contractor. Has any one of you here know some estimate of the cost? Thank you so much
