3D model + video with mascot

We need to create three 3D animation videos with a brand character.

We are considering two possible approaches:

• 3D videos created primarily using AI;
• classic 3D production: modeling, rigging, animation, rendering.
  
  

As a result, we want to obtain:

1. 3D model of the character (for future use).
2. A short watermark animation on a transparent background — 3–5 seconds (for overlaying on videos in social media).
3. Video 1 with the character — approximately 25–30 seconds.
4. Video 2 in which the character speaks — approximately 55–70 seconds.

We have images of the character, texts, and a preliminary description of the scenes. Detailed materials will be provided to potential performers.

The videos will include:

• full character animation;
• body movements and emotional expression;
• facial expressions and lip synchronization with the voiceover;
• interaction of the character with objects;
• scenes in an office environment;
• the possibility of multiple similar characters appearing in one shot.

In your bid, please specify:

1. Approach: AI generation, classic 3D, or combined method.
2. Cost and timeline for creating each video separately.
3. Total cost and timeline for implementing the entire package.
4. Separate cost for preparing the 3D model of the character.
5. What exactly is included in the cost.
6. Number of revision rounds.
7. Whether music, voiceover, and sound design are included.
8. Whether the source files will be provided.
9. Links to relevant works with character 3D animation.
