Scott~! plz..
i wanna know something that
how much normal salary if debut writer's scenario( if it gonna selled)

toomity: There is no 'normal' salary. If a spec script sells, it sells for what the buyers will pay. If more than one buyer is bidding on it, that becomes what is known as a 'bidding war,' which is obviously preferable for a writer of a spec script.

For a schedule of minimum payments for film and TV writing as specified in the WGA MBA, go here. That will give you some sense of the numbers.
