Hi There,
We're Auburn Jam Music production company based in London and we'd love to help you out with this project. We have good experience in composing music for children given a theme - we've composed for audio books, animations, and theme parks in the past.
We've also got top-notch recording equipment and an in-house musical theatre singer and voice-over artist perfect for this work. Will PM you some samples.
Hope to be able to work with you. All the best,
Auburn Jam Music.
