Game plug-in script developer

I am looking for an experienced game script developer to create several custom plug-ins for a World of Warcraft game. Specifically, these need to be scripts for Level up & Progress features. I do not have any existing game code to use for the plug-ins, so I need help from scratch. The scripts will be implemented on World of Warcraft platform. If you have the skills to develop advanced game logic and can meet the timeline requires, I’d like to learn more about your experience. Thank you!
