Reliable cable repairs?

I have a nice custom silver braid phono cable with cardas connectors. For awhile I was tracking down an unpleasant hum in my turntable setup and eventually isolated the cable as the cause (the noise would come and go as I manipulated the system - originally I thought it was a bad component in the phono stage). More so it is the connection between the cable/ground wire and the DIN female jack... anyone know of a reliable repair service for cables?
A soldering iron and solder?
If you are unable or unwilling to make the repair yourself, any local electronics or TV repair shop would be able to do the job. Just be sure to be explicit in your instructions and expectations as may of the folks working in these shops wouldn't qualify as 'audiophiles'. However, they would be more than skilled enough to carry out the repair.
