Hand-Drawn Lighthouse Scribble Overlay Animation

I have a 10-second video clip where the main subject, an old lighthouse, is missing the top. I want to recreate the top of the lighthouse with a color 3D sketch-like raw scribble animation that sits directly on the subject and the light inside slowly flashes. The line work should feel hand-drawn and imperfect—think colored pencil strokes that wiggle slightly, with a slowly flashing light inside the lighthouse top. Target budget is $50 and 2 day delivery time.

You’ll receive the clip in 4K 30 fps MP4 and a photo of the lighthouse showing the missing top to use as a guide. Please return:

• A version of the video with the scribble baked in, same resolution and frame rate.

Feel free to use After Effects, Animate, Procreate, or any tool you trust, as long as the final look remains true to that raw, sketchbook style. Timing is straightforward: the drawing should fade in during the first 2 seconds, then stay visible for the remaining 8 seconds, with the light flashing twice in those 8 seconds.

Attached are:
Photo of the lighthouse with the top - to use as a guide to sketch the top - match shape and color.
Example of scribble animations.
Example of a 3D rendering of the lighthouse top.
A low-resolution version of the video clip to preview (I will transfer the 4K clip by Google Drive link).
