1997 Honda Accord radiator drainage

my car heated up and i inmediately stopped and parked it, as I did not want to run the engine. I waited for it to cool off some and started the engine to pour water directly into the radiator, I then noticed water shooting out under the radiator..i felt the water coming out of a missing screw or something at the bottom of the radiator ,,i placed my finger to stop it and the water stopped comig out,,Is that the radiator drain valve missing or what?
I am a woman and dont know too much about mechanics,,please tell me so the mechanic wont charge me and arm and a leg just to place a drainage valve on the radiator,,i have no money,,
thanks guys,,
