Hi,
you might want to check-out the following links below. Besides, I believe the best/fastest way to find a school where a FI course is available at short notice or even a single person course is to give them a call and see what they say.
FI - Flight Instructor & IRI - Instrument Rating Instructor
Flight Instructor FI(A) Training - Pilot license, Flight Training, Pilot Training
Flight Instructor -
I'm not sure if the following schools provide a FI course, but it might be worth calling them.
Smartaero - szkolenia lotnicze warszawa, o?rodki szkolenia lotniczego warszawa, licencja PPL(A), szkolenie IR(A), szkolenie MEP(L), szko?a latania, latanie samolotem, jak zosta? pilotem, budowanie nalotu, czarter samolotu, wynajem samolotu
