I'm into sustainable farming. my bees are primarily a source of food, candles, soaps, and balms for the family (extended) and for barter. I also raise chickens and rabbits for the same reason. Food for the extended family and barter for other things I need.
It's surprizing how many people right now are willing to work for a couple dozen eggs for a 1/2 days work. Throw in a dressed out hen or rabbit and you have a day laborer. It's the same for fruits and vegetables. This summer I will pay my day laborers with Jars of honey, eggs, meat, fresh vegetables, fruits, and berries.
I'm not running a business (it's against the Trust the property is under) but I can grow and barter all I want.
