You need to deobfuscate the DarkOrbit's main.swf which has 3D which is a lot hard job

then you should write your emulator with .NET and write your packets from the swf inside and then you need someone who knows PHP/MySQL/CSS to do your CMS part of the private server. And in additional someone who knows ActionScript3 to modify the swf, make new NPCs maps events etc etc
