What if I don't want to go ahead after the proposal?
Then you don't. There's no obligation at any point, and the plan is yours to keep. You'll have spent $95 finding out what your script needs, which is the cheapest way to answer that question.
Why can't you quote the rewrite up front?
Because scope varies enormously. A contained 95-page drama with a soft second act and a 130-page ensemble with a structural problem are different jobs, and a page rate would overcharge one of them and undercharge the other. We quote once your pro has read your script.
Who actually does the rewrite?
The pro you chose on the call. The same person who read your script and wrote your plan writes the draft. You're not handed on to someone else once you've paid.
How long does a rewrite take?
Your proposal gives you a delivery date rather than a turnaround range, because the date depends on the scope of the work your script needs.
How is this different from coverage?
Coverage gives you a report and a plan you carry out yourself. A rewrite means a working screenwriter does the writing with you, from your plan, with your vision leading.
Do I still own my script?
Yes. The copyright stays with you throughout, before and after the rewrite. Your pro is working on your screenplay, not writing their own.
