John, I recognize it's a low estimate but I need a very simple speak design for a mobile app on Android. I have another developer creating all the back end services and coding functionality, but they are not designers. The design of the app is generally built, I have logo vector files, screen count, and general design scheme built. Screen count is 16, 12 being same design structure and 4 independent- representing help menus, log ins, and specific function screens. General design should be in current Google flat trend appearance and no more than 6 independent colors. I have a deadline of early May. What are your thoughts.
