Book, Writing, Publishing Question

 I need some assistance, advice, opinions, whatever.

I have a finished novel. It's been edited a few times, but could maybe stand another editing (cause it's been a couple of years since I looked it over).

Should I edit it again? Or well more likely have someone edit it for me since I've read it multiple times. In which case does someone want to volunteer to edit for me?

Also what I was considering doing was publishing it on Amazon as an ebook/kindle book. Does anyone know how to go about doing this? Any suggestions on this? Is there a better place to self-publish like this?

I also have a short story series I want to do the same thing with--once I edit them a bit. Again anyone willing to edit them?

Thanks! It's all original fic so there's not an issue there.
