Ecommerce website and android application

I need to create an ecommerce website and android application for personal use. The website should be accessible on a wide range of devices and the android app should run on supported android devices. The design of both the website and the application should be custom made, no existing designs. This project requires a professional and creative eye, as it will be for personal use. The desired outcome is a secure and reliable website, with a modern and user friendly application, both excellently designed.
