I charge by the page so that my clients and I can work on only what the client needs. There's no need to reset the entire project when you just need help with Chapter Four. It also means I can work on short stories or epic novels and still have straightforward and up-front pricing.
After we've agreed to work together, the operation is simple: 1) Email your manuscript to me. 2) Relax while I edit. 3) Within 7 days, I'll deliver your line-edited manuscript along with a ~4 page Lessons document with big picture issues and detailed lessons.
I earned my MFA in Creative Writing. For those unfamiliar with an MFA degree, it's a graduate degree in creating our own writing (my final thesis is a publishable book), studying both past and contemporary authors, and analyzing the myriad aspects that go into telling a story -- all with published novelists and current editors/agents in the field.
