Short teaching videos for various topics (send quotes)

I am looking for someone who can make short (45-60second) videos explaining various maths, verbal reasoning and non verbal reasoning topics in a clear and engaging way for my tutoring classes.
I am in the process of making slides for each topic which will show the topic and explanations I want in each video. The videos should be easy to follow and animated (these are aimed at 9-10 year olds) and carry my logo at the end. I have attached one slide below for a maths topic to show the sort of information that will be needed in each video.
In total I will have over 100 videos to make, so I haven't put a project price, perhaps this can be negotiated.
