Create an Animation

I would like a simple, but clean animation of an envelope opening to reveal what is inside. The outside, you see the bottom image from the first page of the attached PDF (Mission Generation...) The envelope opens up and you see the inside, which is the giving information. (Second page of PDF) The animation should be a clean, "flat" style, similar to the animation in this video: [login to view URL] Also check out: [login to view URL] - I like the animation style and the look, but the envelope needs to look more like this one: [login to view URL] Notes: - Use Blue Gradient Background (attached) for the background Need this done sooner, will hire someone who can do this today or tomorrow.
