What Type of Surgery or Procedure Would I Need for my Chin/jaw/lip? (photo)

I have asked a question about chin implants before but I think my lip may be an issue. I'm 20 and have had braces to "fix" my overbite. I don't think by bite is perfect and my teeth angle outwards and meet: \ / I know i have a undeveloped jaw and i don't like the appearance of my "weak chin". But my main issue is how my lower lip sticks out. What procedure would fix this? Would i need jaw surgery and braces again or would a chin implant improve the appearance?
