Looking for expert in DB and C# / C++ programmer for MMORPG game server.

Hi, I am looking for an expert in DB and C# / C++ programmer with motivation and energy to provide perfect service which will work with our team to run MMORPG game server. We've got the full game server and client files and we need assistance with debugging the game. Some of the files are probably corrupted, so we need to rewrite them with the right functions. The game running with a C# and DirectX 3D (Direct3D 9Ex) engine base and a lot of MSSQL DB and tables that we need to mapping all the connection and function in Excel file with notes first before debugging. Since the game is up and running there is no need in heavy coding only to fix the bugs and write new codes for a small function that missing here and there if necessary We have a list of main bugs and issues but there are more bugs that we didn’t see yet. The main job is debugging and write some new code if needed. There is a connection issue from the client side to the server side on the VPS. The VPS is running Windows Server 2012 R2. The Local launcher on the server is working fine and the game is running well. We need to work ongoing (play and debug) because we know most of the bugs but still, if we want to make it perfect we need to work together. So please reach me only if you have a good experience with C# / C++and MSSQL any other skills will be great.
