science topics videos project

Hi, I am looking for a video creator who can create series of videos on science topics intended for the students of Class. 4th to Class 8th. The videos should be a mix of amination and actual human video content with voiceover in American accent. We are looking for series of 10 videos each on topics like the Solar system, Human body, Plants, Animals etc. In the first batch, we are looking to create 200 videos. Average duration for these videos would be 8-10 minutes each. All these videos are to be uploaded on our Youtube channel.
