Before polishing a proposal that could be much stronger, you may want experienced eyes on your pitch. When you submit a portion of your nonfiction book proposal, Margot provides you with feedback about how it will most likely be viewed by publishers and what you can do to strengthen it. 
Margot reviews your proposal and equips you to make it shine. Her main interest is to let you know how an agent or editor will view your work and to ensure it's serving your reader. She'll offer clear instructions about what you can do to strengthen your proposal in order to make it as compelling as possible.
Margot reviews your manuscript and offers valuable feedback designed to help you meet your publishing goals. (Caution: don't submit a manuscript if you don't have energy to invest on the back end. With even the strongest manuscripts, Margot will offer ways to strengthen the writing and better serve the reader.)
