I'll do a little digging but ultimately I think that's a fair price. Most fab shops charge straight time when it comes to custom work.
One place I know that does excellent work, a guy I went to UTI with, has a shop in West Chester and they do a lot of work to custom stuff to lots of Jeep builds. D'Antonio Automotive is the place. I'm not sure on the pricing but the quality will definitely be there. If I won the lottery tomorrow, I'd be sending my stepdads 3rd gen there to be restored honestly. His a good guy, has a good team and has quality work.
Additionally, have you ever had your cam bolts changed out or lower control arms? If they have never been touched they will be seized, and your bill will go up because they will have to cut the old bolt out and either put new bushings in or lower control arms all together to finish the job. Just something to keep in mind.
