Design an Android App Mockup/Prototype

Hello everybody, IMPORTANT: First of all we kindly ask you read our project description thoroughly to the very end and only then decide if you are willing to bid for this project considering information you will find below. 1) We have existing Desktop application and need app design mockup. We can send you screenshots of existing Desktop design, but for mobile app we want different design approach and composition. 2) Project could be delivered in two ways: A) Design in PSD, with support of different resolutions, 9-patched, etc B) above plus .xml layout that we can use in Android Studio or working and responsive prototype. A) would be cheaper while B) would be more expensive 3) We will select designer ONLY by approving his approach. For this we will request designer to send us his sketch of our login screen. For now we will not care much about quality, but we need to see approach, composition, color scheme and if it fits our understanding. We also can send you some design examples that we like conceptually. If we like your login screen we also would like you to send quick sketch or approach of one of more sophisticated window (or even we would agree with your description of design in words). Please, consider this before bidding because it might take some effort from you but still not being selected so please do not bid if this way is not acceptable. However, we do not consider this as some kind of contest and it is more the way to check if we are hiring someone that has the same feeling in sense of composition and design. 4) App will have around 12-15 windows, but some of then just simple pop-up with some text information. There are two sophisticated windows in Desktop application that will need some tabing or sliding solutions to display required information. Rest of the windows are pretty simple. Best Regards
