Need 10-15 screens designed for Samsung tablet application. Prototype screens already exist, but need to be redefined and polished by a GUI design expert. Very simple screen designs required due to target audience on non-computer/tablet literate people. Current screen designs are attached so you can see what style we are looking for - nice colors, large buttons, easy navigation (Home, Back buttons, etc.). We are open to suggestions for Top Header and its buttons, as well as if buttons should be on the left side or on the top of each screen.
