Realistic Rotating Christmas Ball Animations

I'm looking for a skilled motion graphics artist or 3D animator to create 8 individual Christmas ball animations. Each ball should rotate in place, with a transparent background, rendered as a MOV file with alpha channel support.
Requirements:

Number of Variants: 8 different Christmas balls
Animation: Smooth rotation in place (360° loop)
Style: Bright, neon, very colorful – think futuristic/modern holiday theme
Background: Fully transparent
Format: .mov with alpha channel (e.g., ProRes 4444 or equivalent)
Resolution: 1000x1000 pixels
Loopable: Yes, animation should loop seamlessly
Duration per ball: ~5–10 seconds

Deliverables:
8 high-quality .mov files with transparency
Optionally: source files (After Effects, Blender, etc.)

Bonus (Not required):
Small sparkle/glow effects while rotating
Some variation in materials (glossy, matte, chrome)

Deadline:
1–2 weeks (flexible for the right quality)

Budget:
Open to offers – please include samples of similar work and estimated delivery time.
