Seeking experienced plugin developer

My friends and I have searched for a long while for a radio plugin similar to Task Force Radio, however does not have an in game VOIP portion. In a sense the plugin designates a group of channels to radio channels in which PTT is forced along with prohibiting users from talking over each other. This plugin could allow tones for a dispatcher and would allow each person with the plugin to have radio sounds when transmitting. Also, it could have the ability to switch between multiple “radio channels” while remaining in the same TS channel where you could only hear and transmit to people in your “Radio Channel.”
If anyone has experience with developing plugins for teamspeak3 please get in contact with me.
We are willing to compensate for the time spent creating this addon.
