I've been through all this pain. Built my own butchery on the farm, bought equipment, registered, been inspected (several times), licensed venison dealer, blah blah blah.
Bottom line? After three years of knocking my pan in, and trying to generate ongoing local business by way of Facebook, local markets, and various local producers groups and initiatives, I am thoroughly disheartened with the entire affair and am chucking in the towel. From now on, my butchery is for me, and the venison I shoot is for me and my family. Enjoyed some of it while it lasted, but to be perfectly honest it's been a complete waste of my time and energy. I may just about have broken even on my overall spending, but if I factored in my own time I reckon I'd have needed to double my returns to make a profit.
Never again.
