How much money would I need to start a self-sufficient farm?

I am interested in eventually purchasing land, building a house and shed, and live by growing my own food and bartering whenever possible. I would raise chickens but no more. Is this a feasible idea (in New England)? ty
I would have some capital in the bank, and would pay bills with the interest. I would only make as much food as I and anyone living with me would need. I would also not have tractors or machine tools whenever possible. If I had to, I would not always barter. And further, I would try to install solar panels and possibly a hand crank generator to provide power.
