Need someone who can build Android and iOS App

I need someone experienced in mobile app development to create an app for both Android and iOS. The development process requires an individual to draw up a draft or source code if they have it available. I am looking for a full application development with design, maintenance and support. My project requires someone with comprehensive knowledge in the field and experience to create a high quality app. The ideal candidate is someone with reliability, excellent communication skills and professionalism. I am looking for somebody willing to help me draft the source code that my project needs. The completion of this project will lead to future projects, allowing for long-term commitment.
