Punkin House Press
I know someone who contacted this company with a "proposal" for a chapter book she's working on. And apparently they've told her they're interested, even though the book is nowhere near complete.
Looking over their website, particularly the FAQs, they don't accept anything unfinished, plus they publish in ebook first, then possibly print later.
I don't see a catalogue on their website. I've seen catalogues on ebook websites before, but not this one.
I also found this posted online.
Not that there's anything wrong with ebooks, I'm trying to advise this author to set her goals higher for her first time out.
