Hello, and nice to meet you.
My name is Mara, I have been Motion Graphics professor and animator for the last 10 years. I saw the video link you sent and I can perfectly build something like that in 5 days since we have all the art and music. I can send you links to my previous work and also I invite you to visit my reviews here in freelancer: 100% positive references, many of them for video creation.
Have a great day!
