Hi Rich,
Please don't take my feedback as criticism, I admire people that do voluntary work so much. I think what you're doing is brilliant and people like you make a real difference!
When I visited your site, I was a little overwhelmed with information, despite the structure of the site being very clean, neat and tidy.
I was always taught to keep the landing page of a website simple, with key points of information that you want to draw peoples attention to. So maybe simplifying the homepage would be a possibility?
Like I say, I think your project is excellent and I hope the website will raise the profile of what you're doing.
