Paid work to project a flight controller

My name is Flavio and I’m a Brazilian living in New Zealand.
I decided to build a manned drone and, since I have a lot of skills to accomplish this mission, engineering is not one of them.
So I’m looking for someone to help me plan the flight control system and to configure it after the building is finished.
As this will be a commissioned job, I would like to be contacted by people with previous experience and successful projects in this area.
Best regards,
