My learning curve as an indie author has been steep, but like sherpas helping inexperienced climbers to conquer Everest, Polgarus Studio has been there for me every step of the way.
They are always a pleasure to work with, not only doing an impeccable job of formatting my books for publication, but also providing excellent editors and proofreaders. I have professionally produced books for digital and print platforms that look as good or better than many I see from traditional publishers.
I would never look elsewhere and I¹d recommend you don¹t either.
