Finding a Backend service call on an application with UI based on FLEX

We have a system that has the following architecture: FLEX UI (a big SWF file as a dashboard), hosted on an ASP.NET solution. On the Backend Server we have a Microsoft SQL server 2008 R2, and on the BACK of that windows services with communication protocols connected to actual devices communicating in specific ports. The UI executes commands for different functions that are sent to the backserver and in its turn to the devices connected to the services on the Backend. We have the full source of the FLEX application, the ASP.net Files, Database Files, and windows services source code. The goal is to be able to trace the call of 2 commands with 2 options each (enabed / disabled). and tell us exactly from C# how to make the calls to the Backend system to be able to execute the same actions that the UI triggers (WITHOUT USING THE UI, meaning that the C# code you deliver should execute EXACTLY the enable and disable functions as if they where called from the UI itself) The task at hand are: 1) Trace the calls from the button pushed on the FRONT end and find our exactly what they do and HOW they call the Backend Exact function with exact parameters, SO THE SAME CALL CAN BE REPLICATED ELSEWHERE USING C#, Please remember you will not be using the UI you must trace the call so the call can be REPLICATED without the UI from the Backend server itself. the call will be implemented on a WCF service that is living on the same server as the application. 2)Write the C# code to execute those commands 3)Deliver the C# code that executes those commands so we can test they work before releasing the money of the milestones we had created. ONLY EXPERINCED FLEX/FLASH AND .NET PEOPLE..... TOO MANY BAD EXPERIENCES WITH NEWBEES.... IF YOU ARE A BEGINNER PLEASE DO NOT BID ON THIS PROJECT. FULL SOURCE OF EVERYTHING WILL BE PROVIDED.
