Schedule a 2-Day North Pole Santa School at YOUR location in 2019, but do it early.
The only costs are for my time. Once I see your files I can give you an estimate of the time required and my fees.
There are no other costs until you order your Proof Copy. For a 200 page book, that should be under $10.00, including shipping.
From then on you only pay for copies you want to personally sell or give away.
