Help me getting started with a permaculture project in the south of Italy

Hello! I have been reading and studying about permaculture for years. Never took a course but I have the bill mollison book and other books about agriculture and permaculture.

The fact is I have trouble starting. My land is 3.3 hectares and there are existing olive trees but they are dying because of a disease.

We have no well at the moment so water is limited

We also want to not spend a fortunate to get started

I really need help because I have no idea what to do, every idea in the end seems hard or unattainable.

I don’t have an house at the moment because it is too expensive to build, maybe I will get some prefabricated shed or something, but in general I’d like to build a long term Permaculture project.

What to do
