Create a Video

Hi, I need someone to create a video that is pretty much similar to the following gif : [login to view URL] What I will provide : -I will provide the perspective mockups (in PSD format) of the layouts (similar to the gifs, i have a bunch of perspective mockups). -I will also provide all necessary assets if needed. However, this is pretty straight forward as I want the same background color as the gif. What I want : -What I want is a smooth bird's eye view of all the mockups moving (just like the gif). -I need the video to be in at least .mp4 and .webm. -The video needs to be of a good size as it is meant to be used as a background image for a landing page. -I will want the project source files of any software you've used. I would prefer that you use adobe after effects. I will be selective in who I hire for this job so you should have some previous work to show me.
