Connection of remote MySQL db through proxy for a C#.Net app

Hi, This is a rather easy one but required on high priority. Our C# based desktop application on a local machine (part of a network) of client needs to connect to the MySQL v 5 database on our remote machine through client proxy. The local machine has Win XP running while the remote machine runs on Linux CentOS v5. We know how to connect to the database remotely but we have not been able to pass our request through proxy server of the client. We are not sure but possibly the proxy machine is linux based and has squid proxy server. The desktop app runs on .Net framework 4.0. We require some good C# developer for this with whom we may carry on future projects as well. Thanks.
