Looking for VR Tour Creation

I need a complete VR experience that functions as an interactive virtual tour, purpose-built for educational use. Think of it as a walk-through “field trip” where students can freely explore, trigger narrated hotspots, watch embedded mini-lessons, and interact with 3D objects for deeper learning.

Scope
• Model or capture each scene in high-quality 3D, optimised to run smoothly on Meta Quest and HTC Vive headsets without sacrificing visual fidelity.
• Build the tour logic—teleport points, gaze or controller-based interactions, pop-up media panels, progress tracking, and an intuitive UI that keeps users oriented.
• Integrate educational elements: quizzes, info cards, or short video overlays that appear contextually as learners explore.
• Supply all project files (Unity or Unreal preferred), textures, audio, and a build ready for deployment.

Acceptance criteria
1. One runnable VR build with no critical bugs and consistent 72 fps on standalone headsets.
2. Exported project folder with clear, commented hierarchy.
3. Quick-start guide: installation steps, control scheme, and instructions for adding new scenes or assets.

I already know the content will be used as a virtual tour with an educational focus, so the technical and pedagogical polish is equally important. If photogrammetry, hand-sculpted assets, or hybrid methods suit the environment best, I’m open to whichever approach achieves realism while keeping performance tight.

Timelines, milestone suggestions, and any past examples of similar VR tour work will help me decide quickly.
