maeve,

Don't know if this would interest you or not, but thought I would pass it along.

A number of organic market growers and nurseries here got a lot help by offering apprenticeships. My ex husband is an herbalist and wildcrafter and his main source of labor has been apprentices for years. They work in exchange for the learning opportunity, usually one day a week.

A local community college also has a program in sustainable agriculture and they pay organic growers as field instructors to offer internships.
