How to make video editing for facebook profile picture?

Question

Video processing

I have an idea to create a video avatar for fb.
*What is the video length limit?
Take a picture of a person (me) in full growth.
The camera shoots a person in a circle, as if a person rotates 360 degrees on a round stand.
During the turn, the person takes a fighting stance, and then returns to the normal position.
Over the video, a text is superimposed in the corner with a description of the characteristics of a person (strength 5, endurance 20).
Tell me, what kind of specialist in my city should I find to implement such an Avatar?
Is it really possible to do this?
Can you briefly describe the stages of development of such a video avatar?
