However, this is your identity -- a visual piece that identifies your company's work. Do you really want to use a template for this? Why use something that other people, and maybe even your competitors, are already using, or could get at any time?
Why not hire a designer to help you identify your needs, meet them, and develop a signature look that's unique to you?

But yeah, what Walter said. Although, so much has already been done in the world of motion graphics. There's this look, or that look that if you customize all the elements of a template to utilize your colors, your fonts, and your logo and images that it most likely won't look like a template. Don't use one that is so cool and specific that it would stand out and be memorable if another company used it.
