Publish Central! Forum Self-improvement Self-publishi..

New here! I'm looking for referrals for credible self-publishing houses in the genre of self-help self-improvement. A legitimate publishing house that includes a staff of great editors (not just a printing press company) without being over-priced. 

I've exhausted myself with my own internet surfing. I'm also aware of there being many self-publishing companies that are predatory. 

Anyone with good experience with a self-publishing company? I'd love to hear from you!
