C# application required to spy on MSN messenger

The application will report MSN messages sent and delivered on the PC that the application is running on. Although I have stated that this should be written in c#, if you have a better way then please describe your approach. The captured data will then be written to a .CSV file. I am a developer but I want the bulk of the work developed for me, therefore, all Source code is to be provided. At time of bidding please supply a description of how you intend to capture the data. Data to be captured: Sender Name Receiver Name Message Date & Time Message Text
