I found a print-on-demand service [IngramSpark] that I’m confident will print your books here. They print the books for Invisible Empire, an openly NS publisher that distributes their books here, here, here and here. It’s worth at least checking.
All the best,
I have had an account with IngramSpark for some time now.
The reason I haven’t published our Daybreak Press books there is that it seems that the same company shut down the Ostara Publications account. There is a clause in the contract you make with them that says they can terminate an account without explanation (will that happen to the NS books you link?).
The other issue is that, unlike Lulu Inc., at IngramSpark, you have to take a lot of tutorials, and that means days if not weeks of work, to design your book covers.
And unlike Lulu, they charge for each book you publish.
At the moment I don’t have the money to publish a single book on IngramSpark. And if a modest amount of money were to come my way, given the clause they have, I would have to find a fan of our books who would be willing to design the covers for free. Otherwise, I would be greatly frustrated if, after weeks of tutorials, my account was cancelled for publishing, say, my book On Exterminationism.
On the other hand, if I received a handsome donation from one of my visitors, I would put the announcement on my blog that I would pay for whoever would design the covers for me. But the donations to my site have gone down since an Australian commenter, who was giving me handsome donations, died.
