Hi Josie Elbiry, yes, as an author myself, I also helped many authors as beta reader. Even though I focus on non-fiction, I may still provide some guidance on fiction based on my taste and writing skills.
It is a good idea to turn your manuscript to mobi and epub formats and distribute it to your interested readers. Based on their feedback, you may further improve your manuscript to prepare for the final version.
It may be useful to obtain some editorial reviews from your readers and attach them as testimonials which can also improve marketing the book at later stage.
You may also use the Goodreads site to obtain beta readers and reviewers. If you are in Goodreads, please follow me so that I can support your books.
