Throttle body rebuild

I was just recently going to have my throttle body redone by Maxbore, and I found out he passed away late last year, RIP. Is there anywhere else that somebody has found to get this done? I have looked and asked around and just can't find someone to do the same service he provided.

 

It's a shame Maxbore didn't do some video's on how to's,,, some kind of instruction on what he acutally did and what kind of equipment he used,,, I'm assuming he "bored" the venturi for one to true it up and then maybe sleeved it to bring it back into spec plus some other goodies.
