For the soundtrack, I have found an ideal piece of music that suits the drama I want in my trailer. The track is "Pop goes the weasel" by Kevin MacLeod. The artist is well known for making royalty free music (no strings attached, no copyright), and as such, the track I have selected is free to use.
Below is a link to the track in question:
The track also sustains a nice beat/rhythm, meaning I can easily edit my trailer to match the beat of the track.
