Android + iOS App Platform Development

We are looking to build a custom mobile app development platform for quickly deploying many mobile apps for Android, iOS and optionally JavaScript. You will be working with a technical project manager from our team to coordinate all the features and implementation. You will be responsible for coding, testing and building all components of the mobile app. We will provide all RESTful APIs to our data and graphic design assets. Attached is an example of the components and UI screens we will be developing. Please provide a time and cost estimate for building the project for each language (Java, Objective C and JavaScript)
