Don`t know in which country you are.

Look at the IR Cameras manufacturers website and look where they have no representants. Contact those.
Be sure that you have the right background - makiing a good consulting talk
to your customers requires a lot of knowledge in physics, electronics, optics,
statistics combined with good experience, otherwise you will fail.
