catfish tackle

i work in a bait shop here in iowa,and having trouble getting the tackle for flatheads,my distribters(sp) just donn’t carry it.i want to find some hooks and sinkers for myself and was wondering where you guys get yours.i’d rather order from another bait shop than cabelas or bass pro.now if the rivers get back to somewhat normal i can tell the boss i’m taking a few days off to go fishing.thanks guys
