Can you help me with...finding sources...obtaining funding...researching case studies...networking...etc.?
You need help. We know and we're trying to create a site here that can do just that. So, you might find the answers to your questions on the web site. Look around. Try a search or two. If that doesn't work, these and other questions like them are best put to the environmental communication community. Join our listserv (Google group) and pose your question there please. Good luck.
