May I make an alternate suggestion. Start your organic farm or garden but sell the produce on a subscription basis. That is, your subscribers pay $40 a week for enough produce to feed a family of 4. You grow the food and deliver it in boxes to subscribers’ homes. Of course this is only a suggestion, price and quantity would be up to you and your customers.
The advantage to you is you have a steady income stream and you know in advance how much of everything you need to grow. The advantage to your customers is they get lots of fresh organic produce at a good price.
If you have a surplus you can sell it at a roadside stand or, start a restaurant.
I would leave the restaurant idea for last because it is the most costly, labor intensive, and riskiest part of the venture.
Double or triple the price
