How much will it cost to fix a nose like the one in the photo?

As a kid, around 11 years old, I fainted and fell on my nose. My nose was bruised for a day. At the age of 13 I got in a fight at my school. A kid punched me in the nose while I was wearing glasses. I was in pain. Later at the age of 17 I noticed my nose looking like in the photo. I became a little insecure. Now I'm 19 and planning on doing a nose surgery at the age of 20. How much will it cost?
