If you have an idea but aren't sure how to put it into form, I am able to write a logline or synopsis to help you get started on your project. All loglines are one to three sentences long and convey what your story portrays in a manner that grabs the readers attention. Synopsis's are summaries of your story and the length of these depends on the length of the story you wish to write. It contains the log line and a detailed summary of your screenplay.
