See if you can get mentoring from local industry
Ask them to come and present any information they may have on how householders could save energy, water and waste at home.
These people are experts in the environmental field and would be able to give great tips and pointers. They would also have great contacts in the environmental sphere.
They might even help to mentor smaller businesses in the area.
Many large companies have Corporate Social Responsibility (CSR) programmes and this would be a very good fit.
