Spare that's really kind of you! Count on me PMing! I have finished my manuscript pretty much so now got to write all the other bits that go with a self published book. Then illustrations!! So really not finished at all yet but the story is.
KDP has a free guide to publishing, it talks you through the process step by step. The hardest bit I found was getting a US tax number, if you're not near London it's a right faff! In the end I got an Employers tax number (as a sole trader) instead of an individual one. PM me if you get stuck at any point, I'll see if I can help.
If you google Madame Guillotine's blog, she has some great advice. I go on a forum called AbsoluteWrite.com which has a self-publishing section where I expect you would find what you need, though I haven't been in that area myself.
I have an idea and a draft so far for a book and am working on it. It's a fairly niche subject so I think that narrows down for me agents/publishers etc. I have read about people self publishing and selling on Kindle etc and wondered if there was a step by step guide anywhere as to how to go about self publishing. <hopeful emoticon> or any sites where this is possible that people have used and can recommend.
