Getting paid to do permaculture... not sure many people will pay you to have a herb spiral or keep a couple of chickens, but they can all be learnt by organising a permablitz at someones house. I think there is plenty of opportunity for someone to earn a living from a fairly ethical business that you could call permaculture, without land or without a huge amount of resources if one is willing. I spent a couple of years on and off wwoofing around learning the trade and can think of at least 6 places that offered me land to use to live and create a business from. There is a great program in Oz called NEIS that can help new business owners get off the ground. One could also go back to TAFE, study their 20 hours per week, get paid Austudy, and begin their own business with the rest of their free time. And there is also business loans going at around 8% interest, which is pretty reasonable on a small lend. I think the main thing holding people back is not their creativeness but that leap into the unknown. There is plenty of land out there to be leased, or used, old people not working the land but dont want to move into town, unsude backyards where grass growing is seen as a problem and contracts can be written up for assurances and fairness. And there is plenty of good business models on growing food, which I think is probably the best way to get your foot in the door or right livelihood. But it is daunting for someone who has been used to collecting a stable paycheck, or hasn't had to organise their own income. But there is also good advice from people on that too, if you want to get out and ask for it.
