app development for food ordering

I am looking for an experienced app developer to create a food ordering app for both iOS and Android operating systems. While I do not have existing designs, I have a rough idea of what I want the app to look like. The most important feature for the app is payment integration. I want the app to have a user-friendly interface and customization options. Ideal skills and experience for this job include proficiency in app development for both iOS and Android, knowledge of payment integration, and experience creating user-friendly interfaces.
