Have you given up on getting an agent?
If you're getting it printed yourself, how are you doing it? Using a local printing company? Using Lightning Source? Going Print On Demand?
So much has changed, just in the years that I've been writing. For example, I've been writing my newsletter, Doing It Write, for 14 years now. When I began, no one had heard of e-books. They hadn't come into being. If you wanted your book published, you queried agents and checked your mail constantly to see if any had responded. (A lot of us still do that today.)
But we're into a new era of publishing. More and more authors are "doing it themselves". This is especially true when it comes to e-books. A lot of authors do their own e-books because it's fairly easy to do.
Even putting your book into print is not all that difficult to do anymore. Admittedly, it takes time and the formatting can be a bit arduous.
If you do it yourself, either in e-form or print, then you also have to do the promoting. Writers who have agents and publishers also find that the bulk of the promoting is on their shoulders, too.
We're now in a new era of publishing. Some of us are adapting and participating. Some are kicking and screaming. Either way, we're now in a new world of publishing.
Publishing is not static. It's a world that is still changing.
