Making money and farming go hand in hand. Very few people want to impoverish themselves and their families. If there is to ever be a widely accepted future for permaculture it has to be proven to provide a decent living for people,especially the young people who have the drive and energy to try something like this.
That said My suggestion would be to grow what you will eat and find a niche. 1. Are their anyone offering higher quality homegrown food in your community? eg. Heirloom vege's 2. If so what Are they growing and selling best? eg. They sell out of tomatoes every weekend. 3. Can you offer a higher quality version of that product? eg.Can you offer san marzano or purple cherokee tomatoes?
4. If not what aren't they growing? If no one is growing say peppers can you offer cayenne or some of those super hot ones like Bhut Jolokia,ghost pepper? 5. Value added. eg can you offer jams or jellies especially if no one else is offering them.
Also know your market. EG. My hometown would laugh you out of town if you tried to sell $3 or $4 a dozen eggs. Doesnt matter how good they are,because people here have plenty of land if they wanted to get good eggs but have little cash. That said I make my own cayenne products like powder,flakes,dried,smoked. I can sell for $40 a pound all day.
That said the last question is Will you market yourself? eg.Buy business cards to pass out everywhere you go,EVERYWHERE! Have a website offer online ordering. Call ALL the local restaurants, Not just the higher end,especially if you are producing more then your other customers can buy. If you want to be sucessfull you MUST push your business and NOT lose the qualities that made you sucessfull to begin with.
But thats just my opinion and I could be wrong
