here is my view in a nutshell.
its all about diminishing returns. just for the sake of argument, imagine it takes 100 acres to make the $$ you expect. also assume you cant make $4000 for a ham, or any other astronomical amount for your produce (at least for the first 5-10 years). the vast amount of work and people you'd have to hire to get the rest of the work done would be astronomical (reducing your profit). if youre growing "500 boxes of apples. 500 peaches, 500 plums, 500 mixed, 500 pears, 500 apricots, 500 kiwi, and so on..." in tree guilds, the harvesting time alone would be incredible assuming you dont hire a small army of people to pick for you (reducing your profit). selling this volume of produce at what passes as a state farmers market here would be laughable. so now youd be hiring additional people to attend other farmers markets for you..... further reducing your profit. these examples of costs you dont seem to be considering could go on and on. consider the amount of time and money to set up the initial plantings on 100 acres, farm buildings, landscape manipulations, marketing supplies and costs, managers, losses due to inexperience and experiments, processing, etc etc. unless youre going to sell wholesale (which wont get you anywhere near 40/lb for pork) to walmart or whole foods or other groceries, youre going to have a challenge to move enough stuff to make the $$ you want before it goes bad.
i never intended to come across as anti permiculture. i think it is a viable option, and intend to incorporate it into my farms business plan (i do have land, and am already developing my farm) along with other viable ideas based on works by elliot coleman, allan savory, grubinger, and others. i will have organic row crops AND edible forest gardens AND free foraging chickens and goats and pigs AND aquiculture. i dont discriminate against other ideologies.
that said, what do i know? the number of people on this forum that ACTUALLY farm could be counted on one hand. who knows if any are really profitable. there arent many permaculture farms to begin with, and most seem geared to feeding the inhabitants around them not with profit. most profitable permaculturists seem to be lecturers and designers, not farmers. most of the famous ones that ive read about either have little experience farming, or never farmed at all. some started farms, then handed them off to someone else and began writing and teaching (for $$$). but once again, im no expert, i dont have all the answers. youll be hard pressed to find any hard facts on what you can make and what your real net income will be. there is just no good info or answers. i dont recommend you take the word of someone who happens to have a website on permiculture...... i suggest you do REAL research on what it takes to have a profitable farm, permaculture or otherwise. that would do you much more good than just taking a six figure # from someone and basing your future on it. but youve read a book, and listen to some podcasts, how can i compare to that??
