Elegant iPad image viewer with InApp purchases and remote control from 2nd iPad/iPhone

I need an iPad app that will basically be an image viewing gallery that can be operated on a single iPad in standalone mode or operated remotely (by wifi or bluetooth - your choice) by another iPad or iPhone. The main app should have these features: - InApp purchase of new “image packs” - Push notification when new image packs are available for download - Display images in groups of four thumbnails or single full page (using shrink/stretch gestures) - Display full page images with or without subtitles (using swipe up for subtitle/down for no) - Allow each image to have a number of different subtitles that can be scrolled by swiping in the subtitle area on the bottom of each image - Allow automatic slideshow if user chooses - Triple tap to make the screen go black (but not turn off – back on with single tap) - App to ignore power saving and auto-off and stay open even with no activity My understanding is this is technically quite an easy app to produce so I also need the developer to help me make it look very professional and elegant. When a single tap, the settings icon allows the user to access the following items in the setting area: 1) Standalone, host or remote control mode? 2) Buy and download new image packs (InApp purchase) 3) Select which previously purchased image pack/s to use in current slideshow a) Review images and subtitles i) View images & subtitles ii) Add subtitles iii) Exclude/hide specific images &/or subtitles from view iv) Reset to default images and subtitles (with “Are you sure” warning) 4) General settings a) Automatic slideshow time between images b) Subtitle font size 5) “About this app” page with links to external website The app will ship with 8 default images and subtitles so the user can see how it works without having to purchase more image packs, but the idea is to encourage InApp purchases. I will supply all images and subtitles to you. I am technically intelligent so the process of making new image packs available doesn’t need to be super-easy, just workable. You will have to tell me what size/format the images and accompanying subtitles need to be in. The remote controller only needs to emulate these features I.e. when connected to another device, the "slave" device should simply behave in the same way as the master.
