Build me an app

We need an app as a platform to include multifaceted information, like videos, websites, articles, live updates, short and long articles, news placards, interactive calculators, etc. We also need a language switch option and a plugin for a google account to record their activity on their account. Rough samples are attached herewith; the app needs to be of quality graphics and interface and suitable for ios and android. Payment is negociable.
