S7-400 PLC connection from .NET application

I need some assistance in how to connect directly from a .NET application to a Siemens S7-400 via ethernet. I will have some questions for the coder in order to decide which approach is best to create that communication (why of using an OPC server, or why using direct TCP connection, MPI, etc) There was not be much of programming involved (this is kind of consulting job via email), but in case we use a library like libnodave, coder needs to provide the basic programming functionality to use it from my C# application. I'm open to hourly rate kind of payment or payment "by the job".
