Online Team File Collaboration Tool

I need help streamlining how my team works together day-to-day. Our biggest pain point is scattered files, duplicate versions, and limited visibility into who has what. To fix this I want an online solution centred on file sharing and storage—something that lets every teammate upload, organise, comment, and retrieve documents without friction.

Here’s what I’m looking for you to handle:
• Recommend or build a cloud-based platform focused on secure, real-time file sharing (think SharePoint, Google Drive, Box, or a lightweight custom web app if that’s a better fit).
• Configure user roles, folder structures, and permissions so each department sees exactly what it needs while leadership can view everything.
• Set up version control, search, and basic collaboration features (comments, tagging, notifications).
• Migrate our existing files from local drives into the new space with zero data loss.
• Provide a quick start guide or short video walk-through so the team can adopt the system immediately.

The ideal outcome is simple: one organised hub where all project assets live, accessible from any device, with clear ownership and audit trails. If you’ve implemented similar file-centric collaboration tools before and can deliver a clean, secure rollout, let’s talk and get this launched.
