video application, Android

We need to develop an innovative application supported by Android OS. The application should have the following functionalities: sms writing and sending to other application or other mail systems’ users. The application should integrate the user’s contacts from the phone’s contact list. The user should Access inbox and sent items. An additional feature is a possibility to record a video, manage the recording, add some effects (sound, lightening effects, etc.) and send to others. The user could choose either to send the video to one or to more persons at a time. We would appreciate developers who would be creative and work appropriately on the apps design, so that it would be easy to use and nice looking. Please state clearly your price on pmb, also demonstrating your previous experience in similar projects. We are also ready to offer you 15% of the application’s revenues if you are ready to lower your bid’s sum by 50% and develop the application. Sate clearly which option you would prefer. Thank You!
