There is definitely an industry format that if not followed gets your script immediately trashed if not followed. I have a book about it somewhere and it gives you all the measurements of margins, font size, line space and etc. I am sure you can find all this info on the internet without blowing $4500. I am sure there is software but if you are savy in MS Word or other, you should be able to set up your document before you start typing.
