Hey, I am looking for intermediate level (beyond the basics) information on how to design permaculture systems without the pricetag. Bypassing my ethical gripe with charging people for ecological tips, does anyone have any good sources of information or advice? Most resources I have found have very little practical information and are almost entirely composed of persuasive arguments for why permaculture is good (if I'm looking at permaculture websites im already sold?). NB: I don't have the money to pay for a certificate course - all disposable income is going into setting up the actual project. Also I remain unconvinced of the value for money in such courses.
