I’ve used them. Pretty sure your meat gets mixed all up with others and their prices are pretty steep.
I’ve seen how well some hunters field dress and care for their meat post-kill. I’ll process everything i shoot at home.
I'm very OCD w/my game I kill. I take mine to a small Czech 1 man processor. His place is absolutely spotless, he's very nice, very knowledgeable (I believe he's 6-7th gen. butcher from Czech.), very reasonably priced & you get your meat back. He's pretty dang old & IDK what I'll do when he quits. He has adult children & g-children but I guess they're not interested in the trade as I've never seen anyone there other than himself. He did 4 deer for me in < 1.5 weeks & it was under $250 for all kinds of specialty makes.
If he did 4 deer for you for under $250 especially with specialty meats, he will be going out of business soon.
It can get expensive to produce and is very time consuming, very.
For many years I have dreamed about opening up my own little business doing just that, and then some. Even mobile cleaning & processing.
I used to have a second job as an owner/operator of a tire & wheel business and I learned this......
Most people want CHEAP and NOW. Most folks are not willing to pay for a quality product.
