Intro animation for HD video

I require an intro animation created for a corporate video we're making. The intro will last only 3-4 seconds and we're looking at using a stock template that can be tweaked. Although, not adverse to creating something from scratch if the stock is not suitable.

This is an example of the animation we require:

The corporate video is about energy consumption / facilities management so we require something that can display energy in some form.

More details will follow once we hear back.

Required for Monday 23rd at latest.
