All I can say is research. I'm a wedding photographer and it is really difficult to come up with pricing. A lot of time is spent figuring out overhead, how much time will be spent meeting, editing, and any other photo process, and how much your art is worth. All in all I make maybe minimum wage - $11 an hour.
WSDA defines a small farm as one where the farmer or farm family participates in the day-to-day labor and management of the farm, and owns or leases its productive assets. Merriam-Webster defines a farm as a : a plot of land devoted to the raising of animals and especially domestic livestock.
In prosperous regions, farms tended to cluster into small villages or hamlets. In less prosperous areas, individual farms were well separated. In Iceland, farms were widely separated, and nothing like villages existed. Typical farm settlements took the form of a central cluster of buildings enclosed by fences. Outside the fenced areas were the fields used for cultivation or grazing.
