Mobil application

I'm looking for a developer to create a mobile application which will run on both iOS and Android. I am open to various technologies, but am not sure what would be most suitable for the project just yet. Additionally, I'm not sure if I need a custom design, or if I can find pre-made solutions. I'm looking for experienced developers who can take my ideas and turn them into a successful application. I am open to suggestions and would like to see examples of your prior work. Please get in contact with me if you have any questions.
