My first reaction to any question like this is, are you sure it's consulting? If the guy comes and fixes the machine, that's not consulting. Does it make a difference if he tells the customer to call someone else to fix the machine?
But in many cases, the only box you can fit this into is the one labeled "consulting."
Seems to me that the seminars qualify for non-SSTB treatment. I don't know the mechanics of splitting that out on a single 1120-S, but I would keep trying.
