Looping Object Animation on JPEG -- 2

I need 3D Flat world map revoving from left to right with all countries (with their names displayed upon hover). I want two separate objects placed on top of the original image and set in smooth, continuous motion—think of a looping animation that never feels jerky or stops. No text effects or changing backgrounds are required; the focus is purely on object movement.

You will receive the base JPEG and a brief on where each object should appear and how they should move. Please handle all frame sequencing, timing, and optimization so the final file plays seamlessly as a GIF (or an equivalent looping format you recommend for quality).

When finished, deliver the animated file ready for immediate use, along with the source file so minor tweaks remain possible later. Smoothness, clean edges, and faithful color retention from the original photo are the key acceptance criteria.
