Hello, saw your demo, and can say, CAN DO IT BETTER... Just need your details what you want, and all footage who needs to be animated. i'm 1 of the authors from ENVATO, so know after effects very well. Also to speed up the process, can buy some templates, or scripts, for animation text...
In this case, video can be done in 5-10 days.
The more interesting part: Whats about the voiceover? you provide this? or be simple video with only music? and more trailer action style?
sincerely,
Ray
