Just a heads up in case your not aware (you probably are)but most of the clinics on here have Skype or similar so that they can give online consultations dude. Also depending on your location it would be beneficial to get some in person advice from different clinics to get a good idea.
I personally would be tempted to leave the crown and concentrate on the front for now.....i only say that as crowns can be a bit of a black hole and swallow up a lot of grafts before they make a significant difference..... and tbh yours doesn't look too bad as yet like the guys said....... You could always address the crown later and maybe use a touch of concealer now and again for now if you felt the need.
Just a thought dude, obviously it's your decision though and a doctor/clinic would be able to advise you much better so i would stick with what the guys are suggesting as they have more experience and knowledge.
I'm not really in a position to give graft estimates myself being just a patient, but from reading other threads and seeing similar cases over the years i reckon Pete and BHR sound bang on with their estimates.....just my opinion
Let us know how you get on dude.
Welcome to the forum by the way.
