How do you find publishers that go beyond just printing?

Hi everyone, I’m a writer who’s been exploring the publishing world while also helping new authors shape their stories. I’ve noticed that some book publishers now focus not only on editing and production but also on book marketing, which feels just as important. With so many options to publish a book online, it makes me wonder are there publishers you’ve come across that truly guide authors from manuscript to marketing? Would love to hear your thoughts.
