C++ Server and Client Class

I require a Server and Client class using C++ and STL. Server Class should be able to handle around 500 connection, its imperative that you use IOCP. I would also require Client class for this server class. We will be using TCP/IP, port should be variable. All communication will be in binary between Server and client. class Server{ static int port; long SendMessage(int ClientID, BYTE* Data, DWORD size); virtual void Recieved(int ClientID, BYTE* Data, DWORD size) pure; string GetIP(int ClientID); } class Client{ int Serverport; string ServerIP; long SendMessage(BYTE* Data, DWORD size); virtual void Recieved(BYTE* Data, DWORD size) pure; } Please bid only if you have previously worked with WinSock2. This is part of ongoing project, we are on tight schedule. More work if you provide us what we looking for.
