Port C# Visual Studio 05 project to Mac

We have a fairly simple program written in C# Visual Studio 2005 that we need ported to Mac OS X. The program collects and packetizes data sent in a specific format over a COM port, displays it to the user and uploads the data to our server using a socket connection. It's simple enough the code is all in one file and it's under 600 lines. ## Deliverables I can provide more details about the functionality for interested bidders, though I won't be able to give out the source code until we choose a coder. I'll provide the chosen coder with the full source code.
