Can I fix a one ear deformity, and how costly would it be? (photos)

Greetings, I was born with two different ears. My left ear was pointy and not as fully developed as my right ear. I want to achieve somewhat of the same side as my right ear, with my left ear. I play with my left ear in the mirror all of the time (as far as grabbing to cartilage and shaping it around to match the other side) I want to know, will this be costly do so? And, will it be possible to remove the bump and restructure the ear?
