Need advise to help make quality bal cables

I want to make my own high quality XLR cables. I can use a soldering iron, use shrink tube and I can buy Neutrik gold pin XLRs.

Is there a REPUTABLE audiophile cable company that will sell QUALITY cable in bulk? Or by the foot? Or are they afraid that 'do-it-yourselfers' might botch their reputation by terminating.

I have:
Emm Labs direct DSD transport
Emm Labs DAC6e
Emm Labs Switchman-3 preamp
Crown Ref I amps (6)

Thank you for any advise.
