I'm always down to help for a mod day. Joe or Woody's house would certainly bring out some helping hands.
On the other hand, if you can't wait, any shop can do the work. It's not any different than putting a lift kit on a Toyota (or any IFS leaf sprung vehicle for that matter)
Coilovers bolt right in, UCAs bolt right in, cam bolts... bolt right in. For the rear, it's an add-a-leaf and shackles. Again, bolts right in.
The ONLY sort of custom work that doesn't involve a wrench or socket would be grinding the passengers side coil bucket a little.
With SPC arms and radflos (PRG Advanced Kit) some people have a bit of contact with the little boot on the balljoint.
I'm a retard and with the help of the guys on the board was able to figure it out. That was over 100k miles ago.
If I can do it, a professional offroad shop can do it.
Good luck! If you decide to have a mod day, I'll do my best to show up and lend a hand.
ETA: does Steve-o at Rugged Rocks do lift installs? He's the most Nissan Nissan guy I know of! Or maybe King Kenny? Or Spencer's friends shop?
