How to find an investor to publish a book for you?

How to find someone to invest in a book when the publishing house can't publish it for you for free?

It can be published by crowdfunding. Nowadays, many crowdfunding websites have the category of publishing/books. You can post your publishing project on it, and make your supporters pay for you by giving them a certain return.

If you want to find an individual or unit to invest, it must be a meaningful/useful book for investors or units. For example, this is a book about local tourist attractions, which can be invested and published by the local tourism bureau. Publishing such a book is obviously beneficial to the local tourism industry. For example, we published an example in which the author was a local poet and wrote some poems for some local primary and secondary schools. The author contacted these schools for book subscription. Because these poems have played a propaganda role for the school, the school is also willing to subscribe to some, and every little makes a mickle, and it has also raised enough publishing expenses. -The Gulu cultural media publishes books.
