sim, há sítios onde isto se faz - e eu gosto

I’ve been receiving increasingly frequent requests to review screenplays, so I am now offering my services as a screenplay analyst.(...)
A few notable highlights: the first five takers get screenplay notes for $99 instead of the regular $125. I offer unlimited follow-up emails on all services. You can get an analysis of your first ten pages, logline, and story concept for twenty bucks, and you can apply that fee toward the full screenplay-notes fee within a year.
