Android app Phonegap and BackboneJS short delivery = high reward

We currently have an Android app built in Phonegap+BackboneJS that is almost ready for deployment but experiences some performance and UI issues. The immediate task is to complete these tasks and make sure the app works perfectly on Android, but future projects are already in the pipeline for a long-term commitment. Task 1: UI Issues Currently the app misses a native feel to it, some screens are missing and icons are not placed right. These needs to be corrected and tasks have been structured already. Task 2: Performance Currently the app doesn’t always respond well when clicking around. Debug app and make sure the current beta does not crash/perform slowly, please check on [login to view URL] Developers from South India are preferred. Since the project is of critical urgency, we’re ready to offer 40.000 Rps if the app is delivered by Sunday night.
