Buy
these, and then solder them to
this.
I'm sure there's a company out there that could do it for ya, but I'm betting that they'd take a ridiculously long time to get them to you, and it's easier to make the cables exactly the length you need em than get some that are just barely too short.
That being said, I am still using George L's and am quite happy with them. One day I may upgrade to something similar using phantom power to power my board, but it's not exactly necessary right now.
