One specialist, complete accountability
I am István Szabó, founder of Sapphire Guardian International and the author Stephen Wayne. I have spent 19 years shaping books and more than a decade serving authors and publishers internationally.
How it works
Send the project type, file formats, target platform, page or word count, and deadline.
I review the materials and confirm deliverables, price, timing, and anything still needed.
Your files are formatted or designed with consistent, publication-ready detail.
You review the result, approved revisions are completed, and final files arrive through Dropbox.
Client experience
“No question—it was a huge work in record time. You did it so beautifully. It was an unresolvable challenge for me, and you really made a miracle and brought it to life.”
“István did the interior layout of our book. He delivered the quality one would expect from a major publishing house in New York or London.”
“He came through and helped us meet a tough deadline while continuing to deliver an outstanding design. Top notch!”
Firsthand publishing
My own published books keep every production decision grounded in the real experience of authors, readers, and publishing platforms.
