Technician Course or Certification

Greetings Kinya,

I've been trying to search the forums in case this topic has already come up. Do you provide any sort of certification for harmonica technicians? I've built up a relatively stable side business here in Canada, but eventually, I'd love to graduate into the realm of "approved" or "certified" repair technicians.

Could you share your thoughts or recommendations on this process?

Thanks,

-Rob
