Pilot Question

I have been experimenting with different things on start up airlines.  I leased 3 737's.  Only then could I see that there were no pilots available, I could not before leasing.  As a startup I have no other planes.  It will not allow me to hire other pilots even to then pay the added expense of retraining them.

What do I do to obtain pilots?

You simply train any number of pilots you require. but it willl involve training costs.

Sorry to be dumb, it doesn't seem to let me hire any pilots to then train.

Nevermind, I figured it out.  Thank you.
