C++ Programmer to fix bug in older software

We have an older C++ application (and the associated source code) that we need to make a change in, but do not have the staff/resources with the experience needed to make the change. The application utilizes a MS SQL database and does not work with the latest version due to decimal precision changes in the database driver. We are seeing the issue detailed here: http://rightondevelopment.blogspot.com/2009/10/sql-server-native-client-100-datetime.html

We need someone with the ability to fix this in the C++ source code and rebuild the software executable.
