I have gone through your description that you are looking for 10 second video cartoons for law firm advertising.
I'm introducing myself here as a 2D Animation and video designer with having experience of 10 years. Now, animation is what I do full-time. My goal is to design tailored animations that, I hope communicate the essence of a company, product, service or an idea.
What I do: ? 2D animation ? Explainer Video ? Whiteboard Animation ? Motion Graphics.
