Don,
I agree with your assessment. I also think a key feature of an AP business will be to actually be able to consistently provide the amount of produce promised. This is why I think a small system would be risky, where a person was counting on 90% or 100% success to meet the expected demand. Farming is farming, and just like any other crop a person can expect some loses. This is what really makes mono cropping an even riskier business. I think you will only be able to not deliver so many times (not many) and your customer will start looking elsewhere. There fore your system has to be well established and you must have some kind of track record to know what you can and cannot provide,
