Do you think self publishing might be for you? follow some of the great authors like Lawrence Block (his blog linki is below) and use the linked tips (link above) from the Book designer blog (Joel Friedlander)
I moved very tentatively into self-publishing. Some publishers who’d reprinted early titles of mine—Hard Case Crime, Subterranean Press—were good enough to furnish word.doc files, and I taught myself how to publish them for Kindle,and had a few others scanned to keep them company. I withdrew them when I made an eBook deal with Open Road for 40+ backlist titles, but soon found myself back at the Kindle Direct Publishing platform, offering uncollected short stories at 99¢.
