@farmerman,
Yep. Rent some space at a Farmer's Market and sell them there.
I think it might be a lot easier to just make big batches of dough using the old fashioned Kitchen Aid and dough hook though. The yard sale bread machines would be enough to get you started so you can make some seed money for the bigger production mixers.
There is a small sourdough company in the Sacramento area that is doing that. They make a sourdough bread with hordes of garlic, garlic juice and aged cheddar cheese. They shape it into freeform loaves, rolls, and the usual square sandwich bread loaves. Every Sunday they were at the local Farmer's Market selling the bread for $7.00 a loaf and it always sold out. They also made a fresh rosemary and olive sourdough that wasn't as good as the garlic and cheese one but was much better than what you can get in the stores. Once in awhile they made a sweet blueberry breakfast bread using the sourdough base. That was also very good.
