Shaina:
Don't expect any of the writers here to be willing to write your story for you, because that would mean to hire a ghost writer, and, as you've mentioned, prices are high, within and without TNBW.
That said, you've come to the right place, because you can receive here a lot of help from other aspiring and published authors by means of critique. Typically, you write a chapter and post it; people read it and comment on it. Some people comment on grammar and constructions, others—like me—on the plot and the story's plausibility.
I’m willing to help and I offer to critique you as soon as you start posting. My suggestion would be to follow Randy Ingermanson’s Snowflake method. You may find information about it here: https://www.advancedfictionwriting.com/ … ke-method/
You can start posting steps 1 and 2 and wait for comments. Then continue with the next steps and keep publishing whatever you write until you end up posting your full novel. Below, you may find steps 1 and 2 quoted from the above website:
“Step 1) Take an hour and write a one-sentence summary of your novel. Something like this: “A rogue physicist travels back in time to kill the apostle Paul.” (This is the summary for my first novel, Transgression.)
“Step 2) Take another hour and expand that sentence to a full paragraph describing the story setup, major disasters, and ending of the novel. This is the analogue of the second stage of the snowflake. I like to structure a story as “three disasters plus an ending”. Each of the disasters takes a quarter of the book to develop and the ending takes the final quarter.”
Don’t forget that the best way to get advice is to read and comment what other writers post, so they may reciprocate. The more writers you critique, the more they may comment your work.
Feel free to email me. Je suis aussi française, mais je vis au Mexique et en New Jersey.
