> They are using no-till methods, the only input is compost and earth worms do the tilling work.

Actually they do use tillers. They use walk-behind tillers like BCS which are common in Italy. These dont compact the soil as much as a full tractor and are cheaper.

My wife and I have a 1000 sqft garden and have been watching Curtis' videos as well. We are considering building a mini-farm business on our property. Other good resources are Jean Martin's farm (http://www.themarketgardener.com/) and Eliot Coleman's (http://www.fourseasonfarm.com/)
