A while ago I raced with a guy called Rhys aka. SouthPawRacer. He has to drive with one hand, but the way he drives and controls the car, it's really competitive and amazing to watch. Plus, he is really friendly and I'm pretty sure he can give you a few ideas or suggestions.
Here is a video of his YouTube channel, you can contact him over there or just watch it for inspiration.
