Captions and slides for 5 demo videos

A sample video: [login to view URL] We have the original HD video, but need a skilled editor to add pretty captions, an intro slide and the final slide. There are 5 demo videos, all under 60 seconds. Some are over 60sec and need to be trimmed to fit into a minute by cutting out pauses. The goal is to keep the original take so that it is true to itself. We are not trying to make the app look better or faster than it is, but some pauses can be trimmed. We will provide the slides. Your suggestions on a soundtrack will be appreciated. We'd like to see some of your previous work relevant to this type of work.
