I am an individual who is very interested in electric vehicles. I would like to know if I could buy electric motors from you to later modify my vehicle.        

Dana TM4 works with and for manufacturers. We do not sell to individuals.

I have an idea that could make hybrid automobiles much more efficient. Would Dana TM4 be interested in helping me develop this new concept?

Dana TM4 focuses on its own technologies.  Even though we find it very interesting to discuss new ideas, our resources are concentrated on designs of motors and generators using PM external rotor topology.
