Hi, Tracy!
You might look for "lifting" companies near you in MN and ask after "tag ends" of Extra Improved Plow or Double Extra Improved Plow. Depending on how much length they use off a spool to replace a crane cable, there's often quite a bit of "tag end" that's too short for another crane refurbish and can be had at excellent prices.
A whole spool of 1 1/4" can be a pretty big affair.
