I have checked the movie that you shared, it is a 1:40 minutes long, and I understood your requirement.
You need a 3 minutes long awareness video and I am interested to develop the animation.
I would like to invite you to see a tyne 2D Animated movie that I made using Adobe Flash.
Do you have a rough storyboard or script or the slides ready that elaborate your thoughts?
Please initiate a chat if you are interested after having a look into my proposals.
Accept proposals as a ballpark estimation, I will negotiate after having a look into the storyboard/ script that you supposed to share with me.
Thank you for your attention.
