Pro bono website for Harmony Animal Rescue - can you help?

Harmony Animal Rescue is a small seniors' association in Winston-Salem that serves about 363 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 15-25 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. Please ask me anything in the questions section. I'll answer honestly and quickly.
