Create a wallpaper app for iOS

Hi, I need an app for iOS. It will be a wallpaper app, there will be a folder with images in the project which must be loaded dynamically and shown at the first screen with an image gallery, once clicked on any image that image will be shown as full screen and will be a menu to share that image, set it as a lock screen... The app will consist in 2 pages. Main Page (Page 1) : - Will be a header with the text "Select Image" - Will show a vertical scrollable image (thumbnail) gallery (in 2 columns) - The images will be dynamically from /Assets/Images folder - When an image is clicked -> go to page 2 Detail Page (Page 2) - Will show the image selected in fullscreen - Sliding the image back or forward with go to the previous/next image (in the same page) - Can zoom in or out the picture with fingers - There will be 3 appicons : Set Lockscreen, Share Image, Save Local (with confirmation messages) It's a small project so please bid accordingly. Smalled bid gets the project.
