Hello,
I'm a writer experienced in both screenwriting and fiction. My first feature, the crime thriller "Deor," is in pre-production at Washington, D.C.-based StonePark Productions with a planned 2020 theatrical release. I consider collaboration one of my strongest suits. In terms of writing, script coverage has always singled out my dialogue, pacing, and ability to world-build.
My bid is on the high end of your budget range, but I remain open to making adjustments once I have more of an understanding of the specifics of the project. (For example, you mention "books" in the plural — it'd be helpful to know how much reading, annotating, and research will be required before commencing on the actual script itself.)
Please feel free to message me any details or questions you may have. Once I know the genre we'd be working in (or, more specifically, the precise material), I can provide writing samples.
Thanks for your time, and best wishes finding a solid collaborator! I know it's not always the easiest.
