I'm with Forrest on this one if you are doing small numbers, the boards and nails or they have what looks like a peg board with loose pins that can be moved to form different wire forms. The pins also have different dia. They are called thing-a-ma Jigs the aluminum one in the photo they also come in plastic in assorted sizes under different names.
You can also get a set of bending wire form pliers,From MicoMark or any of the model hobby sites, Tower RC sell one that is used to bend music wire for the control throws. Jewelry supply shops will have a number of pliers that will have two different shaped jaws or stepped sized jaws. the set from MircoMark is in this next photo along with, all of my wire shaping pliers.
I have been making stainless wire hangers for parrot toys, for over 25 years. with a couple of pairs of custom adjusted pliers.
Cut notches in cheap pliers, either round or plain needle nose.
As in this photo
You can do the out side of spring load pliers if you need to open some thing.
Been there, probably broke it, doing that!
