Develop a native Android application

We would like a Native Android App to be developed for our ride-sharing service. It needs to work on all devices (phones and tablets). You get: 1. Screen designs for the App as JPG files (can be improved a bit during development) 2. REST services to communicate with back-end server You need to: 1. Focus on developing App adhering to the design, and consuming REST services for functionality 2. Develop high-quality App (avoid trivial bugs) 3. Deliver in max 2 weeks (ideally 10 - 12 days) 4. Communicate freely & professionally for any clarifications and show progress every 3 days by sharing APK file (feedback if any will be given after testing the APK file on tablet & mobile phone) About App: 1. App will have around 15 screens 2. App will provide ride-sharing capabilities - post ride, join ride etc 3. App will have a Google Map widget in ride-related screens 4. Simple logic & validations will be expected from the App 5. Some of the data will need to be cached locally (Example: cache user details upon successful login) Regarding payment: 1. Payments will be made in 3 milestones - initial milestone (20%), interim milestone (30%), final milestone (50%) after App is successfully delivered Attachments: 1. Sample screen designs (others will be shared upon start of project) Thanks.
