Simple video edit

Hi guys, we have made a simple 5 minute video tutorial for an employee app and we'd like to add simple background music and some symbols/guides for the viewer to follow what they need to press as we explain the features on the app.

We don't have the right software so we're hoping someone can do this simple edits which shouldn't take more than 10 minutes with the right program.

This is just the start but there will be more work as we will need to create more tutorials for our employees.

Thanks.
