We do all that in-house at InterNACHI. We write our own material, Kate is our in-house editor, Vega is our in-house graphics artist, and Kenton, Ethan and Rob are our in-house researchers. Paige designs all the book covers but if you look at all our inspection textbooks you’ll get the inside joke regarding this, LOL! (her check mark cover designs are all the same, she only changes the color).
If you are writing an inspection book, we’ll publish it for you, promote it for you, and not take a cut.
InterNACHI is the world’s largest publisher of inspection books, one of which became a best seller, 16 times over.
