I don't know exactly how much it costs, but I know where the operation is best. That's BK Toyo Plastic Surgery Hospital in Korea. It's the most famous plastic surgery hospital in Korea, but now you don't have to go to Korea. Their dean, Dr. Jin Bingjian, regularly goes to China for surgery, such as Wan Chinese Medicine Hospital. A friend of mine had a nose wing reduction operation there, and the effect was good. She is much more beautiful and recovers quickly. Details include the price. You can consult their Chinese website.
