Can anyone help me find a paid summer job on a farm?

I’m studying agriculture. I’m thinking about starting a farm in the future. I’d like to work for a successful farm to see if the work suits me. Here is what I’m looking for:

*Start/end dates between May and August 2011. Ideally 2 months.
*Pay. I simply cannot afford to work for free right now.
*Housing provided or very very cheap.
*I am specifically interested in herbs, fruits/orchards, livestock and greenhouse work.
*The business is well-established, not a hobby or side-business but the main source of income for its owner and is in the black. I want to learn from a savvy businessperson.

Anyone know of anything? I am willing to travel almost anywhere.
