I have experience with soundtrack composition, which has to be made quickly and rather long. I've got experience on both SoundCloud and Spotify.
For this project, making such long files requires both speed and effectiveness, while not losing the quality of music. I have several production utilities that will aid me in making long, pad-like music with brief, varied cuts to keep the music interesting to the listener (although not too engaging, as this is simply meditation music).
For the copyright, I'll simply give the file to you, and that'll be that.
I hope you consider my portfolio appropriate for this job, and that you consider me.
I hope you find what you are looking for in this job, and best wishes to you.
