Jim, Brady and I combined for that seat. The seat is based on my adzed and hand shaped seat. Brady did the scan and then fixed up the result a bit and also mirrored one (better) side to the other.
As far as pricing goes, best to take that up with Brady and have him quote your scan. Your in good hands with both Brady and Jim, consummate professionals who do the job exceptionally well.
I can say, I was nervous to outsourcing any part of my projects, but I’m very glad that I did.
I approach this from the perspective of wanting to make many chairs, but this was cost effective for a short run all the same.
