No specific company right now. I'm just wrapping up the first draft of the current book, I'd estimate something like a year out until I'm close to ready to publish, but the story is awesome and I'm making good headway.
I did Amazon in the past so I could get on their KDP platform. It was great as it made it more accessibly to people, but I don't know that it's actually worth it because of the lack of control that you mentioned before.
