othmar is right here, time is money and if your in business lost time equals lost revenue. Because I wanted my meat to be a certain coarseness, I ended up spending 3 to 4 hours just mincing until I bought a 1HP mincer and now it takes an hour (ish) to do appx 50lbs of meat through a 4.5 mm plate. I still have to butcher the meat etc which I am getting faster and faster at with the practice. I guess you could always get your meat either ready minced or ready to mince, what you have to do is weigh up your time and how much that "costs" to how much you are willing to pay for the meat ready done for you, but then that kinda misses the point on making your own sausages in the 1st place !...At tleast your in the right place here as there are loads of people with lots of experience to help you out. I started making sausages and bacons etc after I had done lots of research and read lots of posts here and other places, now I like to think that I know what I am talking about, however, I still have lots to learn and at least I know if I ask a question here there are those who can answer it !
The other point that othmar made regarding how you "sell" your sausages is a valid one too, you could be giving your products away for your guests breakfast, but how about selling them to the guests too, you have a perfect chance to let them sample your products at the table, and have a price list on the table too so they can take some away if not fresh then frozen.....might be worth looking at....Are you going to stop at sausages or do black pudding too ?...Then you have bacon and even haggis.....
