I need 2 additional short animation clips created for an ergonomics training video

Information for the business: We sell web based health and safety software systems
Industry: Technology
Design details: We develop and sell a range of web based health and safety software systems and need the video we use for correct workstation setup to be updated to latest office environments.

We will 2 additional short animation clips created and rendered with my guidance and explanation. We already have the first 4 clips, but we now need to add 2 clips for the same 3D standing at their workstation and the workstation moving from sitting to standing and setting up their posture and where to place their hands. We will also need 2 images, 1 of the worker standing poorly and 1 of the worker standing correctly.

This will be required for each of the setups below.

1. Laptop computer (already have the sitting animation files, need the standing animations created)
2. Single monitor setup (already have the sitting animation files, need the standing animations created)
3. 2 monitors (both screens used equally) (already have the sitting animation files, need the standing animations created)
4. 2 monitors (one monitor used more than the other monitor) (already have the sitting animation files, need the standing animations created)
5. 4 monitors (all 4 monitors used equally) (already have the sitting animation files, need the standing animations created)
6. 4 monitors (the top 2 monitors used more than the bottom 2 monitors) (already have the sitting animation files, need the standing animations created)

Will need 4 versions of a fully animated training video for each computer and screen setup above.
Ideas for the visual style: Modern office environment - Already have design
