Kids’ 3D Promo Cartoon

I need a short, engaging 3-D animated cartoon that will promote my product to children. The piece should be colourful, upbeat and simple enough for young viewers to follow while still conveying a clear promotional message.

Here’s what I have in mind:
• 3-D animation style only—no 2-D or stop-motion.
• Storyline and visual tone tailored specifically to kids.
• Final runtime around 30–60 seconds (open to your professional advice).
• Delivery of a full-HD video file plus any project source files so I can reuse assets in future campaigns.

If you can take the concept from script through final render—modelling, rigging, animation, basic sound and a child-friendly voice-over—that would be ideal, but I’m flexible if you prefer to collaborate with my in-house team on certain stages.

Please share links to previous 3-D cartoons aimed at children, outline your proposed workflow, and let me know how soon you can turn this around.
