Community Partnership Updates Website Build

I need a clean, easy-to-manage website that will act as the central hub for our community-focused partnership. The single goal is to keep members, community, and supporters in the loop by regularly posting updates, listing upcoming events, and offering resources.

Core needs
• A straightforward content management system—Wix, WordPress, Squarespace, or any similarly intuitive platform—so non-technical volunteers can update information, add posts, events, photos, and PDFs without relying on a developer.
• A resources section where PDFs, guides, and external links can be grouped logically and searched.
a members only login section
• Responsive design that looks equally good on mobiles, tablets, and desktops.
• Basic accessibility best practices (alt text, proper heading structure, legible colour contrast).

Please keep the build lightweight; I would rather have a fast, stable site than an overloaded theme.

Acceptance criteria
1. All listed sections function as described on the live domain.
2. I can log in, create a new event, attach a resource, and publish an update without touching code.
3. Pages load in under three seconds on a standard mobile connection.

When you reply, focus on experience building similar community or nonprofit sites and briefly outline the approach you would take to hit the above criteria.
