mobile skype add on

I need skype add on for android mobile , this project is POC and the contractor which will do it well will get the project. The add-on should be operated when the user try to do video call. In order to present the option for the add-on to catch the video stream - The add-on should put watermark on the video stream - but if it can be seen that the add-on "catch" the stream and redirect it to skype - the watermark may not be implemented (will be consider while developing) Requirements: 1. in the code there should be a function (hook) which get the real time stream 2. the watermark should be on the stream itself. 3. it should disturb the skype functionality 4. it may be separate app but it should start auto when the user try to do skype video call 5. minimum delay on the image processing (it should enable video call with reasonable delay,that the user wont feel it) 6. support android 2.2,2.3, 3 only bidders which can show that they have the ability to do it will be replied. payment terms: - 10% - advance - 10% - roadmap for the solution (description of how it will be done) - 10% - demonstrate on android 2.2 - 10% - demonstrate on android 2.3 - 10% - demonstrate on android 3 - 25% - deliver working product (after bug fix) - 15% - deliver all code with inline comments and instruct how to build the project - 10% - month after delivery and bug fix if needed
