Would you still start at 4am in the morning? I was contemplating "retiring" to work at a local cooperative bakery that makes similar things, but their shifts were at horrible times that felt like it would ruin my health.
I would not wake up at 4am. I am much more interested in making the bread, baking is the easiest part. I would hire a night owl to do the baking. Everything else can be baked for lunch.
