Interactive 3D Animation for TubeSac Web

Freelancer Job Brief: 3D Model & Product Animation for Web Scroll Story (TubeSac)
Project Title
3D Product Animator / Modeler: Realistic continuous-bag waste stand animation for interactive web scroll

Project Overview
We are building a modern, interactive product landing page for TubeSac (a continuous-cassette waste bag system).

As visitors scroll down the page, a 3D animation must smoothly scrub forward through the entire bag cycle: from an empty cassette loaded on a stand, to filling with waste, cinching with a cable tie, cutting between ties, and immediately having a fresh bag ready.

We need an experienced 3D artist (Blender, Cinema 4D, or Houdini) who can accurately model the hardware, simulate realistic plastic film/cloth dynamics, and deliver the final assets ready for web integration.

The 5 Animation Stages (Timeline 0% to 100%)
The animation will be scrubbed via scroll on the web (total duration approx. 150-200 frames / 5-8 seconds at 30fps):

Stage 1: Setup (Frames 0 - 30)
TubeSac stand (stainless steel tubular frame with cassette holder and bag cassette ring).
The plastic tube is pulled down from the cassette ring and tied at the bottom to form the initial bag.
Stage 2: Waste Loading (Frames 31 - 70)
The transparent/translucent bag fills with representative lightweight commercial waste (packaging/paper/bottles).
The bag naturally sags and expands under weight.
Stage 3: Pull Down & Double Tie (Frames 71 - 110)
The user pulls the filled bag downwards; fresh material feeds smoothly from the top cassette.
Two cable ties (or clip ties) are placed around the neck: one closing the full bag, one creating the bottom seal of the next bag.
Stage 4: Cut (Frames 111 - 150)
A cut is made between the two cable ties.
The sealed full bag drops away onto the base / floor.
Stage 5: Reset & Ready (Frames 151 - 180)
The freshly tied bottom sits ready in the stand, demonstrating that 0% of plastic bag capacity was wasted and the next cycle is instantly ready.
Deliverables & Technical Specs
We are open to your recommendation on the best approach for web performance. Please specify which method you will deliver:

Option A (Preferred: Highest visual realism & 60fps performance)

Pre-rendered transparent WebP/PNG image sequence:
180 to 240 frames rendered at 1920x1080 (or 1440x1440 square), transparent background (RGBA).
Clean studio lighting with soft shadows onto a contact ground plane.
Optimized file sizes (under 100 KB per frame via WebP lossless/near-lossless).
Web-ready compression test.

I have uploaded our brochure and also a product video so you can see how the system works.
