Copywriting for iOS app

We are looking for a copywriter who will be using screenshots and list of features write an app description for AppStore, for the promo web site, and one to be released to press. We are an IT company based in Russia and this is our first application for iOS. It's called "DraftCraft" and it is a simple yet powerful blog publishing tool. We have taken out everything but the essential features. As Antoine de Saint-Exupery said "Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away," and we have made our app as perfect as it gets. We need press release with full description by July, 1, and AppStore and promo site description by July, 8. List of features and screenshots are attached.
