If I have understood your requirements correctly, my bid is a partial one: what I can do:
rendering the fully completed animations upto 1080p / 30-60 fps , 2 minutes can be completed approx. 3 days.
Relevant Skills and Experience
I have completed animation works in Blender, one of them for example, is a planet and its moon circling. This is just a simple example.
Available system: 2 * GTX 1070, approx. equivalent with 12 of 4core i7 workstations.
Proposed Milestones
$6 USD - Project Milestone (animation 1)
$6 USD - Project Milestone (animation 2)
$6 USD - Project Milestone (animation 3)
$6 USD - Project Milestone (animation 4)
$6 USD - Project Milestone (animation 5)
These above bids are very low, I am aware of it, but maybe it can allow you to hire a better animator, by dividing the task to
1.) completing the animation files
2.) preparing the videos (which is the computationally intensive part).
