Write your own manuscript instead of hiring a ghostwriter at $50,000. Spend roughly $3,000 on a professional editor, then self-publish through Kindle Direct Publishing with freelance designers from Fiverr. Total: about $5,000 to produce a book that could hit Amazon bestseller status.

If you're on tight budget, I would say write the book yourself because hiring a ghostwriter is pretty expensive. We charge $50K. One place I would invest money either way is on an editor. You will not even recognize your book. It can be that dramatic. And you can find like a solid editor for like a couple grand. Definitely put aside $3 grand, let's say, hire an editor you feel good about. That's something you definitely want to do. Publishing, you could self-publish, go through Kindle Direct Publishing. You'd have to get like freelancers or whatever to do like the book cover and formatting, but you can find that on like Fiverr. And again, Fiverr is not going to be like the highest quality of book cover designer, but again, if you're on tight budget, so you could honestly publish your book and become an Amazon bestseller yourself, probably with about like $5K.
It's a no-brainer decision as a minimum, I would say.
