Party Photo App

I require an iPhone app that will sell the weekly party events photos to people that attend the parties First tab, the app needs to show and search weekly events by name, place and location, tapping on the event will show thumbnails of the people and photos but not a high res photo, if they wish to acquire the photo, they can purchase the album in app, and the photos will be downloaded to their photo album Second tab will display the weekly events going on around Sydney, and people will be able to put down their name on guestlist to the various events, which will be sent to various organisers before the guestlist closing time, and also highlight the events that I will be attending Third tab will have a contact me section, where people can send me a email inquiring about shoots and prices I also need prices on updates, such as adding additional tabs
