Mobile development -- 4

I need an iPhone app. I would like it designed and built. Photo uploader application. The application supposed to let the user to choose multiple pictures from his phone, and then choose the sizes that he want the pictures to be printed and them click 'send' - while clicking 'send' the pictures will be sent to the cloud (amazon or dropbox) and will be ordered in folders by date and print size. The steps seems to be like this: 1. Open the app 2. Advertisements shows (slider, banner) 3. The user click 'choose pictures' 4. The user see all his pictures ordered by his phobe folders. 5. The user choose multiple pictures. 6. The user click 'next'. 7. The user seemes to see all the selected pictures, the user need to choose the printed size for each picture. 8. The user click 'send pictures'. 9. Anyone tgat have permissions can see the files ordered by date and size in the cloud online. Need to take care for this problems: 1. Online - cant be after minutes - the files seemes to be uploaded asap. 2. Chunk-in : upload files by the phone seemes to be sometimes problem because of the internet connection, wifi, 3g 4g ect.. the uploading seems to managed right with the currect messages.
