Where to find a mobile app developer for my music company?

Spotify and SoundCloud are probably familiar to everyone, but Pandora and Tidal are not. There are numerous music apps available, but they are not well-known enough. I also want to start my own music business, and I'm looking for experts to make an amazing app. I received a recommendation to use the Top mobile app company to complete the task. As a result, I've come here to ask for recommendations on additional app development companies.
