Hi Ramone, Glad to see a fellow author exploring beyond the boundaries of traditional publishing. I've got one ebook published, and several more in the holding pen, so I guess you could say I've got experience.
Let me ask first, are you planning on publishing it yourself? Or are you looking into any of the many ebook publishers out there?
In general, finding a reputable e-publisher is like walking through a mine field. There are good ones, and there are really bad ones that you want to avoid at all costs.
Self publishing is, IMHO, the better route, but there are several steps that will also cost you. You still need ISBNs, which, when I purchased mine were $225 for a block of 10. That's the smallest number you can buy, btw. Then there's a fee whenever you register a number with R. R. Bowker, but I don't recall right off the top of my head how much it is.
You still need to get a registered copyright on the book with the Library of Congress. The last I knew that was $35 or so (current fees are available on the Library's website).
Then of course, there's your own website so you can market the book (THE HARD PART). But, since you're here, you've already found the best host on the planet.
The advantage of self-publishing is, you have more control because everything is in your name. The disadvantage is, you have to do all the work yourself. I took it as a learning experience.
Actually, I started a tutorial on my site to help others avoid some of the pitfalls out there (some of which I learned the hard way), but I still haven't finished it yet. Bad D.J.! No Cookie!
Let me get together some of the tips and links I collected and get back to you.
And hey, best of luck if you go this route!
