What type of surgery to fix poor facial aesthetics?

I am unsure on what type of surgery I would need. I have a gummy smile, lip incompetence, mentalis strain when I close my mouth, and a receding chin. I was also a mouth breather for two-thirds of my life, if that influences anything. I've had braces already but I'm still not happy with how the lower-third of my face looks. What type of surgery can fix these problems? How much will these surgeries cost?
