Finding a flight instructor

Hello! I'm living in europe, but now I decided to take the step and
become a real pilot with everything and such. I want to travel to the
United States next summer and get some flight training there. I already
have some flight time (~40hrs) on C-152s, C-172 and some much more
powerful planes. Being a pilot also helps me with my career (I'm
working in aerospace). I don't want to go to a flight school but
instead pay a free instructor to teach me. But I couldn't find anything
on the net, I only found flight schools. Can someone here help me or
give me some advice? What I'm looking for is a free experienced
instructor (ex-military or active military pilot preferred) located
somewhere in the California, Nevada or New Mexico area. If he has it's
own high performance plane that would be even better.

Does anyone know where I can look for a suitable instructor? Or perhaps
someone already can recommend a instructor.
