2. These days, publishing houses make money first, only publish at their own expense-that is, you have to pay the "ISBN fee" (although the Press and Publication Administration prohibits it, almost 90% of books are published in this way), and then print at their own expense (you can find a publishing house with low printing fee and go through the formalities in the publishing society), and then underwrite all of them yourself.
3.ISBN fees vary from publishing house to publishing house. Let me briefly introduce: there are1.5 ~ 20,000 famous big publishing houses; Second-rate publishing house with Chinese prefix, 1~ 1.5 million. Seven or eight thousand at the provincial level. Three or two thousand I'll give you some. I know all this. I can't talk about them here, so this is a report. If you really need it, send me a message.
4. Then there is the printing fee. You can contact a familiar printing factory to see how many copies to print and at least how many. Knowing these expenses, you can contact the publishing house and see how much it costs, which adds up to the total money. Once you have raised all the money, you can go on.
