You could use a 24" round piece of plywood, drilled in the center with a coffee can or similar sized cylindrical object in the middle... The roll fits down onto the can and rests on the ply. Hang it from a rope in the center with some sort of thrust bearing to keep it from twisting... Wire Caddy! (you can buy Wire Caddy's too.)
Or just buy 1000' rolls, they come on a spool, but you knew that already...
You can also quote 110-12 and tell him it's a code violation (I love 110-12!)
