That's my point. Find that crafter who's making sinking minnows and AH'ing them. Message them, saying "Hey, if you're on can I make an appointment to get some crafting done?"
Alchemist gets a customer that buys up minnows/SM's in bulk for a fair price. Fisher gets full stock of lures to work with. Win-win. Heck, if you could find a safe spot near where said fishers are dropping lines full of said lures, I'd be setting up with a mule and a pile of minnows in it for the win.
