Illustration-animation of events and objects for lecture telling

Industry: Education
Design details: Illustrations and simple animation needed of events, places and objects that can be used as a creative resource in my voice-over science (Earth science) lecture. Looking for around 40+ illustrations. Illustrations do not need to be very detailed.
The simple example of animation is

Text will be voice-over.
Illustration/animation must follow speech. Avoid unwanted sounds, characters, or annoying pen writing on a whiteboard except the case of formula (if you're courage for animation). Just story telling.
Finally, lecture will be as video presentation with voice-over.

So,
Please see attached example notes. Open to suggestions.You would need to research the courses and add in video and pictures. Some pictures will be real results of research. I will provide them.

If you can give me a quote based on the docx attached I'll have a rough idea on how much will cost. Text counts 8000 words.

All intellectual property and copy rights must be transferred at end of the project to me upon full payment please.

Best,
Vad
