DIY speaker cable made from cat 5 type cable

I am looking to make my own speaker cables according to Jon Risch's notes that I found at: www.geocities.com/jonrisch/s2.htm?200611.
I am having difficuilty finding a source of cable other than having to buy a 1000 ft spool or buy premade computer cables with the wrong type insulation. i would also prefer more that 4 twisted pairs per cable. Anyone have a solution or left over cable they would want to sell?
Thanks
