Ventilation in Structures is Poor

I am developing a ventilation system for all types of structures (commercial and residential) for which I have a patent pending. I need some help with the control system for the mixing chamber and need to talk to some one that is good with PLC's. This new system will use an air to air heat pump and make it more efficient, as well as ventilating the structure with a more efficient air. The range of the heat pump will also be increased and the need for backup heat will almost be eliminated. Is there someone out there that can assist in this type of project?
