Help !

I bought a screenprinting and monogramming business 15 months ago. It has not done well. Most of the machinery was old and we were not able to keep it running. We have learned a lot. All the hard way. However we do have a two head melco machine that has gotten us through. We were struggling with rent and overhead so we moved everything to our 40 by 60 heated polebarn located on our property. Now here's my big problem. Somehow the move did not do well for the machine. It will not run. It comes up with a stepper motor error. We have replaced all for fuses but it just blows them again. I need to know if there is a repair person in the area. We are located in Browerville, Mn which is about 70 miles west of St Cloud. Does anyone know of a reasonable repair person who knows Melco.
