You might want to contact Mike Merner at Earth Care farm. They have leased fields to farmers before and they have great water and a greenhouse. It's the oldest organic farm in Rhode Island, so it's already certified which is handy. They are also a composting facility so the soil is rich and
compost is abundant. I don't know what their current plan is, but it would be worth a try. If they already have something going for all the fields, they might be able to point you towards someone else. There is plenty of farmable land in southern Rhode Island, some landowners week let you farm it for free. (Usually not with a well and greenhouse though...)
I'm curious, what are you planning to grow and how will you sell it? Do you have much experience farming?
