Overhead Venn Diagram Animation

I’m refreshing my site’s hero section with a short, looping MP4 that feels like we’re hovering above an architect’s desk while a hand sketches a Venn diagram. No live-action footage is necessary—you can generate everything with AI, 3-D, 2-D, or a hybrid approach—as long as the final look remains realistically lit and textured.

Here’s what I have in mind: the camera stays fixed straight down on a large sheet of white/off-white paper taped to a drawing board. A right-hand enters, alternating between colors of a paint brush or sticks of chalk to rough in four overlapping circles. As each circle appears, the hand briefly writes its label in clean, legible lettering: “Investor,” “Entrepreneur,” "Entrepreneurial" and “Traditional.” The motion should feel human and the final frame looks like a freshly completed diagram ready for the viewer to see the final product.

Because this clip will autoplay on the top fold, I need it silent, 8–12 seconds long, and exported as an MP4 at 1920 × 1080. It should restart seamlessly without a visible jump. Please also supply the working file (After Effects, Blender, or whichever tool you choose) so I can tweak colors later if needed.

Deliverables:
• 1920 × 1080 looping MP4, 8–12 s, no audio
• Source project file with all assets organised

If that brief matches your skill set, I’d love to see a quick storyboard frame or style test before you dive into full production. I will provide a graphic of what the final Venn Diagram will look like, unless this is something you can do yourself with my pending description.

I am not that familiar with MP4 production like this. So please provide a rough estimate of project cost.
