Write descriptions for two android apps for Google Play Store

I have two android apps that will soon go to the Google Play Store, and I need some features and descriptive facts spread out into an interesting and formal description. It needs to be on par with other top selling Google Play apps' and fill out the page well. One project is a card game, and the other is a camera app that is more technical. I can give a feature and small descriptive information, and will be available for contact for any questions to help complete the description.
