Website help for a women's cooperative: Acacia Seniors' Association

Acacia Seniors' Association is a small women's cooperative in Santa Rosa that serves about 310 people each year. We've been running on word of mouth and social media, and we need a simple website with information, volunteer sign-up and a donate button. We have the content, logo and photos ready. We need someone who can design and build it, and show our volunteer how to update it. We'd estimate 10-15 hours of work. Ideally it should be fast on mobile, accessible, and use inexpensive hosting. We have a domain already. Please reply with a link to similar work. We can't pay, but we can offer a reference, a public thank-you, and a lot of thanks. I never thought I'd be the one asking, and I'm grateful for every bit of support.
