Like smalljaw stated unless you want to get into some serious money, you can buy premolded jig heads either painted or unpainted and skirt material. Then you can put them together yourself and see how it goes.
Check places like Cabelas, Bass Pro, Stamina Inc, Barlows, Jans Net Craft, Lure Craft, and Fishing Skirts for supplies.
For example: Barlow's has football heads for around $.60 each and skirt tabs in a kit for around $.30 each. So you could put together jigs for $1.20 per jig.
You can make the a whole lot cheaper once you have you lead pot, fluid bed, powder paint, lead, etc. But unless you buy hooks by the 1000 and skirt materials by the 100 you won't have a lot of savings.
