Hi, i need some experience or thought, which one is better self publish book or sponsored? How much will it cost if choose sponsored?

"Self-published authors can make between 40% – 60% royalties on the retail price of a single book while traditionally published authors usually make between 10%-12% royalties."
I honestly haven't published a book yet, but I thought some research might help.
If you are leaning towards earning quick money, some status, and/or validation, getting your book sponsored should be your path.
If you are leaning towards potential long-term wealth, freedom, and/or creativity, self-publishing should do the trick.
Of course, both of these options have their cons and whatnot, but this is a simple summary of my quick research.
As I said, I haven't got the chance to publish a book myself, so take this information with a grain of salt.
But I do hope I was able to help in some way

You can try both, however unless you manage to stand out in some way (unique experience or amazing writing skills) you will find it difficult to get a conventional publisher to accept a script. You have nothing to lose by trying the self-publishing route and you will learn a lot about book-selling along the way.
