Audio/Video/Chat Application

I need a good programmer/programmers to modify an existing voice, webcam and chat application (My Phone) to include the same features as MSN these are as follows:- - text chat, text conference - video chat, video conference, video mail (if the user is not online the possibility to leave a video message) - voice chat, voice conference, voice mail (to be able to leave a voice message) - file sending The software already has most of the functions but needs to be modified, the most important aspect of the modification is voice clarity and webcam conferencing (using the best codec) with the ability to leave a webcam and or voice message. Please bid if you or your company has experience in this field and can provide examples. I have put a limit of price for this project because, programmers have already developed VoIP applications or can customize an application that has the same features as "myphone". Please do not bid if you are not able to modify the “my phone” source code and produce a no obligation demo as I have realised with previous bids, it is very difficult to nominate a programmer without the ability to hear the quality. The bidder must sign an NDA upon start of the project. Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer).
