Coming in to agree with pmmg; writers write. It's really the only rule. Writers write, and the only way to get better is to write more.
Fussing about publishing before you're ready to bring a manuscript out for public consumption, be that a reading audience or agents and publishers, is putting the cart before the horse. Publishing is for later. Now is for learning.
Let's say that again: Now is for learning.
But, you asked about what publishers can offer. Distribution, mostly, though even that's changing. Everything else, no matter the publishing model you choose, is on you. So, when the time came for my team to choose, we went indie. Attached are examples of what you can do on your own. My wife makes beautiful books. (No idea why they're rotated. Sometimes this site hates me.)
