I am pretty close to publishing, at most a month away. My editor is almost finished
If your editor hasn't yet finished, you'll be pushing it to get the book published within a month.
Once you've received your editor's suggestions you'll then have to go through them and act on them. Editors don't change things in books, they suggest changes which the author then agrees with, and makes, or disagrees with, and ignores.
Once you've done that you'll need to check the book through and make sure it is cohesive; and you'll need to copy edit it too, to make sure it's error-free: copy editing is best done after a break from the book, and if you hurry into it you'll miss things.
I'm not sure there's time to do all that as well as you can in less than a month.
and I hired someone to format to get it ready for print and Kindle.
There's a huge difference between "formatting for electronic edition" and "typesetting for print edition". Make sure the person you've hired understands the differences.
Once the book is typeset and formatted you'll need to proof read the book, to check for errors again. It's astonishing how many can be introduced at the typesetting stage.
My question is, what else do I need to do? I haven't written my "blurb" yet and am wondering how long it should be. Is there anything else I am missing?
To complete your book you need a jacket design, front matter, an author bio, back cover copy... look at the structure of a trade-published book to see what's required.
But then you also need other stuff. A press pack is a good idea: a press release with some promotional material to send out (cover flats, or electronic images of your cover in a selection of sizes, author photos, and so on).
You might be wise to send out review copies in advance of publication, to help build buzz; you could see if you can get quotes from other writers or personalities, which always helps; but these things are better done in advance of publication, and if you're hoping to publish in a month you don't have time.
