How do I resolve my uneven jaw/chin? (Photos)

So initially I assumed that getting braces would sort out the cross bite of my teeth, but I then realised that it's my uneven jaw that is causing the crossbite and uneven chin, and possibly even my uneven lips (my right jaw bone is much more pronounced that my left). My teeth are also started to overcrowd and get even more wonky due to my wisdom teeth growing though! What's the best way to go about getting this sorted? And would it cost a lot of money?
