Multi-Platform Book Publishing & Marketing

I have a four-book self-help series in the works; the first two manuscripts are complete and their covers are finalized. My immediate goal is to release these titles as eBooks, paperbacks, and hardcovers through Amazon KDP, followed by wide distribution on Barnes & Noble, Kobo, and Google Books...
