We are looking to make a new video for a demo of our Company's software products.

We are looking to make a new video for which would act as a demo for our software. Aimed at potential new customers.
It would be approx 2 mins long max. I would produce the video to record the physical demonstration of the software being used but we would require voiceover and some other screens/animations intermingled in with the shots of the software. Main intention is to project our message across and make it interesting to view for a potential user as oppose to a standard product demo.
We are looking for somebody who could provide the creative input as to how it looks and how its put together and then produce the video.
