Video and voiceover

Hi,
I have a powerpoint presentation that I would like converted into a promotional video.

All the slides are in place with the text, script and images.
I need someone to make it look more professional and also add some background music and a voiceover.

This is for professional services so it needs to be crisp, clear, modern and to the point conveying our message. I can provide an example of a video that I would like it to look like for your reference.

Please provide previous examples of videos you have done in the past.

You will need to sign an nda for this and not market it as your creation.
