Build an iOS App for a technology blog

My name is Vincent and i'm the Co-Founder of iPhoneism.com. Its a new website geared towards Apple news in general and to jailbrea/unlock solutions, support and tutorials in particular. We are proud to say that in just a matter of months, the site has grown well past half a million unique visits. We would like to get an app developed for our website. For reference, may i suggest that you check out the apps of Mashable, TUAW and Engadget to get an idea of what we are looking for. Basically, its just going to be an app that is going to fetch the latest news from our website, will have integrated sharing options for readers to share any article with the various social networks and as well as the ability to save articles for offline reading. What we basically require, are the following features: 1. App displays news stores from the website 2. App allows articles to be stored for offline reading 3. App allows people to share articles via email, to Facebook, Twitter etc etc. 4. App provides links to Twitter feed, Facebook page, and YouTube channel. 5. App displays the latest video uploaded to the YouTube channel on the Home page. 6. App sends push notifications when new articles are posted or new videos are uploaded to YouTube.
