iOS Developer for eReader App

Hi - iOS developer needed for project with in-app subscription management and social media integration, beginning in June. Our project is a Newsstand-enabled iOS app downloaded through the App Store, offering a simple but polished way of delivering ongoing instalments of an illustrated ebook to iPad & iPhone. Instalments of the ebook will be sold in-app under a subscription model, with new content being automatically downloaded to the devices of active subscribers periodically when a new instalment is released. Urban Airship, or a similar third-party provider, could be used to handle the back-end of the subscription service - more info here [login to view URL] The ebook reader part of the app will be relatively simple but beautifully rendered, containing the usual set of reading tools for bookmarking, adjusting font-size, brightness and colours etc. While the ebook content will be predominantly text, instalments will also contain some links and images. The app will also offer a storefront on top of this, allowing users to • subscribe to future instalments on an ongoing basis • unlock an instalment by signing in with a Facebook or Twitter ID • purchase back-issues (if subscribed) • enter promotional codes for subscription discounts • and manage access to content that a subscriber is entitled to. Additionally, there will be some straightforward social-networking integration using Facebook and Twitter APIs, allowing users to post or invite friends from inside the app. We would like to hear from a friendly and independent iOS developer confident on all areas of the above functionality with high availability in both June and July 2012, interested in potential further work to upgrade and maintain the app beyond its launch. Many Thanks
