Want to do a Hair Transplant

I want to do a Hair Transplant, FUE method.
I hope one surgery will be enough just to fix my frontal hairline.
I dont want it lowerd or go to some extremes, just a bit fixed so my frontal hairline looks more natural.
So i need an opinoin and your thots on the matter.
Im 29 years old, i mostly buzz my hair, and i have the same hairline like this for about 10 years now.
Think i need more then or about 2000 / 3000 grafts or ?

3000 about right at 50 graft/cm
