Literally hand-winding pickups takes a long ....ing time. No fun. Some people will pay good money for it but it takes a good amount to really be worth it.
If you're interested in doing this, the simplest way to go is to grab a cheap electronic motor from some place like Radio Shack and using that as a drive. I'd measure out the right length first, as counting the turns is a little annoying to do electronically if you have no prior experience, and then set the motor to go, 'scattering' the things around just for the whole 'authentic' hand-wound sparkle.
