What sort of budget are you looking at? I just went through this all myself.
Options would vary from small hunter/restaurant grade machines for $4-600, to butcher shop grade units for $1200-2000+. Biro and Pro-Cut are well represented up here for higher end machines.
For the mid range units they can be a bit more hit and miss. The Tre-Spade ones look fairly nice for the money. I'd be leery of quite a few of the smaller restaurant machines I looked at to be honest. There are of course the LEM and Cabela's machines too. They'd be similar to the restaurant grade machines. For small quantities like you are talking about they'd probably be just fine in all honesty.
A heavier unit like a Biro, Pro-cut, Butcher Boy, Berkel, ect will grind a LOT faster than the equivalent size and power rating of mid range grinder. It comes down to a combination of them rather under rating the power output, and the head design. I have a 1hp #22 Berkel, and the smallest diameter part of it is where the plate sits. The throat is massive, comfortably 2-3 times bigger than even a #32 size consumer grinder. Despite being smaller and less powerful on paper, it would outwork a 1.5hp #32 consumer grinder by probably 2:1. Now do you need something that will grind 20-30 pounds a minute for what you described? Probably not. But it's worth keeping in mind that going from a $6-800 high end consumer grinder to a $1200 entry level butcher shop grade unit is a BIG upgrade. Pro-Cut makes a nice 3/4hp #12 for around $1200. It will out pace a consumer #32 in real use. I would have bought one of them if I didn't find a deal on this used Berkel
