SharePoint Policy Document Intranet

I need a SharePoint-based intranet that excels at document management, specifically for our internal policies and procedures. The goal is to create a central, secure space where staff can quickly locate the latest approved version of any policy, track its revision history, and, when authorised, submit updates through a simple approval workflow.

Key elements I expect you to configure include:
• A clean site architecture with intuitive navigation to the policy libraries
• Metadata fields and content types so policies can be filtered by department, owner, issue date and review cycle
• Version control and check-in/out enabled by default
• Granular permissions that let HR and Legal manage documents while the wider team remains read-only
• An automated review/expiry reminder system to keep policies current
• Fast, accurate search scoped to the intranet (leveraging Managed Properties where useful)
• A branded landing page that highlights recently updated or soon-to-expire policies

I’m comfortable providing the initial policy files and our brand assets. You’ll handle setup in SharePoint Online (Modern experience), configure the required lists/libraries, build any Power Automate flows for approvals and reminders, and deliver brief hand-over documentation or a recorded walkthrough so our admins can maintain the site.

If you have prior examples of SharePoint policy or document management portals, please share a link or screenshots when you bid.
