Android Tablet app for sales agents - UI design

An Android UI/UX expert is needed to design the user interface of a field sales app.

Sales agents will use an Android Tablet device to register orders. The attached document contains the order registration procedure (this can change during the project).

You will be given a list of data elements that the app must request as input or display as output. (Data will come from a web service back-end, being developed parallel to the Android App.)

You will have to design the UI that handles this data in the most efficient and ergonomic way, so the agent can use it 8 hours a day. We expect you to create either
a.) a mock-up in Balsamiq or similar UI mockup tool or
b.) a set of Android UI XMLs that can be given to coders.

The project will be iterative, with each version tested with the client and refined. We expect to create the first working prototype within a week of assignment. The overall project duration is 4 weeks.

Note1: the app will be used in Hungary, in Hungarian language. You are welcome to provide screens in Hungarian if that's your native language, otherwise do it in English and we will do the localization. We will also provide you everything you need to know about locale specifics, such as address format, order form fields, etc.

Note2: we are posting the UI/UX design and programming in two separate jobs. You are welcome to apply for both jobs if you have the expertise.
