if it's something important shot on the TechPan I would strong encourage you to develop it yourself or send to professionals to do it. TechPan, based on industry's knowledge worldwide is best done by Steve Woodward from DR5 lab in LA. (
www.dr5.com) Steve has been synonymous with Techpan and is able to develop it from a negative into a positive. ie. he can make it into a B&W slide. But his charges are on the high side though but they know what they are doing.
The other alternative is to send it to Maestro printer Desmond Kwan locally for the next best option.
At the moment, I am not sure if the printers at Ruby or Riceball photobookstore knows how to handle this film. As far as I know, the developer mix they used is not optimised for TechPan.
