Android Function

Looking for an android developer that can accomplish one simple task. I don't care the method and I don't care what needs to be done to the phone. Here is the task: Option 1. Inject a sound into the phone call Option 2. Transfer a phone call when a user attempts to put it on hold. If you as a developer can accomplish either of those tasks, send me your bid, and we will get this project rolling. I need this done in two weeks or less. The deliverables on this project will be one of the following: An android application that can demonstrate injection of sound into the phone. or An android application that can demonstration transfer of the phone call when being placed on hold. I need this as an Android application that I can install on an Android phone, and show it working to my partners. I will accept a project that can demonstrate either of those capabilities as a solution as a completed project.
