Interactive SharePoint Decision Tree Development

I need a custom SharePoint app that transforms a complex Excel decision tree into a clickable, interactive format. The decision tree has over 30 decision points, so it will require a professional touch to ensure smooth navigation and a high-quality UI/UX. The interactive decision tree only needs to be fully functional on desktop devices.

Key Aspects:
- Convert a complex Excel decision tree into a custom SharePoint app
- Ensure professional UI/UX
- Provide a guide for future edits

Please share your timeline and cost for this project.
