We need an apps prototype for demo purpose. The apps is about paying parking fee for vehicle via mobile phone (iOS platform) using credit card (no need to include payment gateway at the moment, just a working screens). This is for demo purpose only. The apps prototype is quite simple, we don't need a fully functioning apps but the apps flow must be working.
We would also expect the developer is able to suggest on the functionality and willing to enhance the existing flow to a better flow.
We would expect the developer to be flexible in terms of discussion timing and actively responding during the apps development.
We would expect the apps prototype to be ready in 1.5 - 2 weeks time.
Please see the attached doc for the mock-up but please suggest if you think you can do better.
