Appliance repair person

I’m looking for a person how can repair a plug on a sewing machine for me. There seems to be a short or something in one of my machines plugs (it’s an industrial sewing machine). After some trouble shooting it does seem to be an electrical issue not a mechanical one. Does anyone have a person that they could recommend to take a look at this for me? Thanks!
