To improve the profit I was going to suggest Createspace, then I read the article. Then I felt embarrassed for even thinking of recommending Amazon printing to anyone ever. Unfortunately Createspace support has never been great, and the transition to Kindle Direct has lowered the level of support even further. Their PDF restrictions are sometimes nonsensical and whether or not it gets approved seems to be blind chance. You can spend days resubmitting the same PDF like a gambler at a slot machine. Win some lose some. I always thought it was just me, but reading the author's experiences shows this isn't the case.
