Design an App Mockup and UI ( Create Prototype )

Design a app UI and associated pages to be viewed on a mobile. This basic prototype will be used to show the skeleton of the product to necessary people. It should therefore be elegant, clean, intuitive and scalable around the features I define. I have a rough sketch of how I think it should look like. However, it is not a guideline, it is something I have been working around in my capacity in graphics (which is nil). I therefore require your talent to make me look good. Please feel free to ask questions and show your interest in this very small project. If this design is a successful one, you will have the option to create the entire mobile mockup and future UIs of the product. To seek your interest, I, the project owner, am an alumnus of Symbiosis with relevant experience in mobile apps and my partner is an alumnus from IIM. We look forward to working with you!
