Hello sir,
My name is Sander and i am a 3D animator, also motion graphics artist, currently working as an art director in a big company. (DOT Digital Group Brasil)
You can check my portfolio here, or i can send you my website after, if you are interested.
Also, i´ve done im my early days as an 3D generalist, a short movie about a dry wall system, where we had to show how was the house putted together. If you need, i can also send you this movie, it´s an old movie (2005) but it has some examples.
That video that you showed as an example, you´ll need someone that knows how to animate the objects, camera, post-production (to create those transitions to transparent object, and the particles) and i can handle all of that for you.
What do you think? Let me know if you have any question about the proccess.
I´m looking forward to hearing from you,
Sander.
