3D Interactive Educational Website

I need a visually stunning, scroll-animated website similar to https://theyearofgreta.com/ but with customizations:

3D Sculpture & Space Background

Replace the phone mockup with a 3D sculpture of a man standing on Earth (Blender/Spline/Three.js).

Background: Space theme (stars, galaxies, etc.).

Smooth scroll-triggered animations (GSAP/ScrollTrigger).

Shared Community Calendar

A public, editable calendar (like Google Calendar) where:

Anyone visiting the site can view/add/edit events.

Real-time updates for all users.

Basic features: Task names, times, descriptions.

Preferred: Custom solution (Firebase/Supabase) or Cal.com integration.

Additional Requirements

Mobile-responsive design.

Fast loading (optimized 3D assets).

Clean, modern UI/UX.

Budget:
12,000–14,000 INR

Payment: 100% after completion (milestone-based negotiable).

Timeline: Flexible, but goal is 4–6 weeks.

Ideal Freelancer:
Portfolio with interactive 3D websites (GSAP/Three.js/WebGL).

Experience with real-time databases (Firebase/Supabase) or calendar APIs.

Strong UI/UX design skills (Figma/Adobe XD).

How to Apply:
Share relevant past work (especially scroll-animated/3D sites).

Confirm experience with shared calendars/real-time updates.

Proposed tech stack (e.g., React + Three.js + Firebase).
