Good publishing companies?

Real publishing companies pay you for the right to publish your work. You pay nothing upfront, and you get an advance against royalties (of thousands of dollars) which you do not actually have to pay back if the book never makes that much in royalties.

Every real publisher works that way, and any other kind of deal is a scam.

If you cannot get published by a real publisher, you just are not good enough. You need to find a different hobby.

You should never pay to get a book published. A book is your work and you should be expected to be paid for your work. To pay for your book to be published is to be sucked into the world of the Vanity Press. What a publisher will pay for a book depends on the quality of the bookIt depends and the author. Every publisher is capable of paying a large advance if they think the combination of author and book are likely to be a bestseller. That's why authors have literary agents to shop their work around publishers looking for the best deal. It's all about expect profits - can they sell the book to Costco, Target, and Walmart as well as bookstores? Is it likely to be a New York Times bestseller? Is the author likely to appear on TV programs to sell the book? How has the author sold before?

Go to a bookstore. Look at the books for sale. See the names of the publishing companies listed on the spines of the books? Those are the companies you're talking about.

The legitimate, traditional publishers pay authors, not the other way around.

Vanity presses charge the authors money. Their books are never carried in bookstores.
