Hi,
I'm a Filmmaker & Motion designer. I'm able to do work as the reference you've posted.
I would need to know how long do you want the video?
Are you providing art direction or do you need it?
Is music and/ or voice over required?
Regarding Payment, it's ok if it's done after the work is done, however, I can deliver the final video with watermark until the payment is done. Otherwise, we would need to make the payment in two times: 50% at the start of the project and 50% at the end with final delivery.
The numbers of reviews must be set before hand.
Cheers,
Van
