Certified Technician?

So my wife and I have a home based business with 6 heads. A combination of the desire to expand and an aging machine have me looking for a new multi head machine.

I'll be retiring from my current field in the near future and plan on giving my full attention to our embroidery business.

With a new machine I not only want to be able to use it, I want to be able to fix it if necessary. I want to know it inside and out. Also making money on the side fixing other people's machines would be a nice side income.

I am interested in hearing from anyone who is a certified technician with Barudan or Tajima in particular. I am curious about the process of becoming certified such as time involved, where the training is, and a rough idea of cost.

Thanks.
