Now, with the possibility of a fresh draft in hand, some people will be looking forward to editing and publishing. To this, I have a word of caution:
I'm not one of those naysayers or Negative Nancys who wants to quash other self-publishers and throw up barrier after barrier to keep the from pushing that "publish" button, but I do want each self-published book to go out as the best version of itself. Not every book has the potential to be a best-seller, but I do want each and every book, and each and every author, to be the best it can be.
And for this reason, a quick read-through of your hastily written NaNo project before uploading it to KDP is not necessarily the best way to go. You're riding that writer's high, flying on your accomplishment, and nothing will bring you crashing down faster than an honest beta reader or professional editor pointing out the parts of your novel badly in need of improvement.
However, for your novel to be the best it can be, beta readers and editors are needed. Even the best rough draft is just that, rough, and deserves more attention from you. So print out some copies to have beta-readers comment on, go through it yourself with a fine-toothed comb to fix anything that you know needs fixing, and if at that point your really set on publishing, I can't recommend enough the importance of hiring an editor.
There are a lot of great places to find editors. Reaching out to your writer friends on social media, or finding out who your favorite bloggers use/used (thEditors for me) is a great first step. A quick google will turn up dozens of good options, as will a trip to a freelancing site like Upwork or Fiverr. You can also head over to my own Editing Services page, where I offer beta reading, content editing, and copy editing services below market rate.
I strongly recommend that, before you hire anyone to edit your novel, you have them edit a sample of it first (1000-2000 words should be enough). If they're unwilling to do this for free, I'd move on to someone else. Paying someone money to do a poor job is a waste of money, and refusing to pay for a service--even a crappy service--can give you a bad name in the writing community. So do your homework, and when you're ready, do what it takes to make sure your book is the best version of itself before you go to publish.
