Need a Repair Tech in Iowa

I have a SWF 1501C in need of repair in Marion, IA (near Cedar Rapids)

Anyone know of a tech that services my area/machine?

The one person we used that was SWF certified I don't think he knew much about the machines. We are having issues with our machine and can't find anyone. I think we are going to have to StitchIt Inter'l come up to Urbandale, IA to fix our machine.
