If you become your own publisher it will open so many opportunities. If I can do it - so can you! Just go on Bowker.com and read up. Buy a block of 10 ISBNs and 1 SAN. Within 3 weeks they get emailed to you, with instructions. Go back on Bowker.com and get into your 'website section' and get started.
From there go to Lightning Source and get your book set up with them, making sure your book is marked as returnable.
After your book is ready to go, start marketing/promoting your heart out. I wish I would've known all this 11 yrs. ago, it would've saved me a lot of heartache and money!
