Dissatisfied with lower face, what doctor/procedures should I be researching? (Photos)

I have always been dissatisfied with my lower face & side profile. The corners of my mouth have always been downturned, my face seems wide when I smile, I have no jawline & I have submental fullness, my chin dips on the sides & doesn't feel like it follows along my jaw bone. I also have issues with jaw clicking & locking & my upper lip covers my top teeth a bit. Should I be considering a maxilofacial surgeon & what procedures would give me a slimmer face and fix the issues above?
