As has been said the 1st thing you need to do is go get your medical, don't bother with looking at prices of different courses etc If you can't get a medical then thats it.
I myself and slightly colourblind and so cannot get a class 1 medical in europe, I'm going to have to hope that I can get one in the US or Austrailia if I'm going to have a hope of having a professional flying career.
