"I'm sort of like a post-modern vegetarian; I eat meat ironically."
Not the first gig to offer, what does one call this, cow on demand? Though usually it's more of a buy a whole cow deal, or team up with a few others and share the cow, or well, whatever. For buying big a big large freezer is of course advisable.
This description though, I mean, killing in the field? What? Wouldn't that like traumatise the rest? Seems like the reverse, ordering traumatised cow when you'd rather be extra special nice about the killing. Or you'd have to be doubleextraplus specific. "The FIRST cow out of the trauma patch, please." No doubt there'll be a premium. For being nice.
