You might also check with Swain's to see if they carry jig molds or R & R Marine. However, if you want to buy the mold and hooks, I'd look to Cabela's; you can find them online at
www.cabelas.com. or you can call 800-237-4444. Both Cabela's and Bass Pro also carry really good jig heads-- the best come with either Gamakatsu or Owner hooks. As long as you get the larger hooks sizes, you should be OK for strength. If you don't get the mold, you can also take a split shot and crimp it to the 90 degree bend in a jig hook. It's not the best solution, obviously, but if you crimp hard enough and then hit it with a bit of epoxy, you can make a credible jig head. It might be a way to get started while you're waiting for your mold.
Also check out the craft shops for "craft hair", it makes a great winging material.
Here's something else that I've been thinking about-- instead of tying a jig, use some of the smaller soft-plastic curltail grubs. Berkely makes a great looking pink and white walleye Power Grub that should kick steelie tail. Or you can cut a pink worm in half and use that. Unfortunately, I haven't had a lot of time to play with this, but now that work's slowed down, I will be-- if I can get away from this fly fishing...
Good luck.
