Cost to get rid of extra columella? (Photos)

I've wanted to get surgery on my nose for quit some time and finally going to do something about it. I feel like my nose looks fine if I don't smile but once I smile the bottom of my nose turns into a triangle and looks really ugly. I like the rest of my nose and feel like everything else looks good besides the end. Also is there ushally payment plans or is this something you have to pay for all up front.
