Write an Iphone & Android app - Photography App - UI and Coding

IPHONE AND ANDROID APP We are specialized in wedding photo and video. We would like to have an app that allows a client to follow up their job progress at every stage of production. 1. Set wedding or event date and client's name 2. Have a progress bar and client receives update notification when production updates info. 3. Clients can contact us through the app 4. Client can review or approve artworks or any job through the app 5. When clients pick up there photos CD to proceed with their selection before we print, we set an update for date of pickup. From that date, we need to be able to set a reminder/another date where the client shall definitely submit their photos selection and shall receive a reminder every day until we approve that the client has submitted his photos selection. If a client is late in submission, then the app shows how many days he is late. 6. Production Steps for photos prior to progress bar in order are: Wedding > Transfer and Backup > Photos CD for selection > Client's selection > Retouches > Pagering > Photobook design > Sent to supplier > Printing > Shipped > Received by production > Quality Control > ORDER READY. 7. We shall be able to set each parameter. For eg. If a client has not chosen photo book option, we shall be able to remove all the parameters after RETOUCHES 8. The app shall allow us to propose promotions to clients at any time.
