make an app

I'm looking for an experienced app developer to create my dream app for both iOS and Android. The main function of this app will be music related. My timeline is flexible so I am not in any rush for the app to be completed, but I am looking for someone who can dedicate their time to create a fantastic high-quality product. I'm open to any suggestions and input that the developer may have, as I have limited app development experience. Looking forward to hearing from qualified professionals!
