Square face - v line + jaw reduction?

Hi all, I am a newbie here. I haven't done much research on the PS clinics. I have a square-shaped face and would like to have surgery to improve it. I am not really sure which kind of surgery is suitable. Do any of you who have done more research or who have the same experience as mine can provide some suggestions on the kind of surgery other than v-line. Do you have any idea how much does it charge in average for just v-line surgery?

Besides, I would like to know which clinic you have...
