I was able to buy Belden cable on ebay and the right angle neutrik and barrel neutrik stereo plugs just last year. Comes out about half the price if you do it yourself, but there is a trick to making quality cables that will last. The Belden cable is old school, but still good quality relative to what they have these days. Maybe look into modern mogami or canare cables that are purported to out perform some of the top of the line cables of 20+ years ago.
As for who can make them around here, Hogan and AO guitars come to mind off the bat. And waldo too.
