Some marketing methods:

1. build a strong brand name and logo. One which can be easily remembered.

2. work together with local governments if they are willing to cooperate or can decide to support you (guess this you have already tried?)

3. Do an unusual public relations event. For instance build a marketing stand with colorful fruits and vegetable stands on a public place where nobody ever would assume to see one. Like a bridge or a Ponton swimming on a lake. Put up a fine dinner table with glued on dishes and food and put it into the middle of a public square like in front of a museum or elsewhere.

4. Invite under ever circumstance the local press to cover it up. You might be doing it illegally (as a guerrilla action) but fear the punishment or you have to ask the authorities in advance to get permission but that might cost you something you cannot afford?

5. try to cooperate with a university like in my telephone book example.

What I try to say: collect unusual awareness either through eye catching installations or cooperations with artists who are willing to work for free. Engage a painter or sculpture to do something with the fruits and vegetables to raise public attention. Ask to get a stand at art festivals or other events.

Try to win a celebrity for a PR-event. But all this also needs at least some money.

In order to get the attention you like you must do not only one but a couple of events throughout a year. This you will need a budget for. Maybe you can find a sponsor for that.

... Oh, and 6: Hire a marketing specialist who is as well himself a fan of organic food and burns for the project. Don't hire someone who only wants a job :)))

.... aaaand.... maybe get in touch with expert perma culturists like Sepp Holzer from Austria. Maybe he will visit your country eventually or is anyway on a trip and ask him if he can be of help. I don't know, maybe he is busy but maybe he will have an open ear?
