Flat 2D Explainer Animation

I need a short (60-75 second), character-based animated explainer video for my product, AQQAI. The complete script is already written — every scene, all dialogue, timing notes, and visual direction — so you'd be animating an existing, finished script, not developing the concept from scratch. The video has 7 scenes and uses one recurring character design reused across 5 characters (recolored or given a small accessory each — a scarf, glasses, a hat — rather than five fully distinct designs), which is a deliberate choice to keep production manageable. Style should be simple and flat, in the tone of a modern explainer video — approachable and clean, not a heavily detailed or painterly look. The story: one confident character appears to always have the right answer, until several similar characters are asked the same question at once and their answers are compared — revealing the first character was simply never being checked, not that he was smarter. A calmer, fifth character steps in to point out the mismatch rather than adding another guess. It ends on a short, honest closing line and a simple end card with the product name and URL. I can share the full script and shot list directly once we're in touch — happy to answer questions about pacing, tone, or specific scenes before you quote.
