Which Surgery to Lengthen my Lower Half and Give Better Defined Jawline and Chin? (photo)

Hello, i am a 23 year old model, with my work i always get to hear you have a bad jawline and stick your neck out. The problem is that i have a thick neck and my jawline goes fast into my neck. Also when i have a beard then i have a bit off a double chin. I am thinking of maybe a sliding genioplasty, chin implant, necklift but no fat 10% (maybe tighten or cut muscles) or jaw implants. Other advise would be welcome, already many thanks. greetings, Kevin
