This is just for future reference. Companies such as Browning or Boston gear usually work through a middle man supplier such as Motion Industries (thats the one I've used in the past for such things and had good luck with great lead times). Through them you can buy gears or gear stock and they sometimes do some custom broaching work depending on the case. Also some of these companies carry other things like fittings, pneumatics, bearings, etc. Other good resources are MSC and McMaster. Your design does look pretty good though.
