My greatest contribution to this point I would have said was Wesley Seminary, but things just seem to get worse and worse. My friends tell me I need to just wash my hands and stop fretting over it. Maybe God will do a miracle.
My current writing project is Biblical Hebrew for the Novice. It's a 15-chapter tools approach to Hebrew with a Udemy course and YouTube videos to back it up. I'm desperate to finish it but also have a day job. Here's a video that gives a sample of the approach.
Another new project is a Udemy course I'm calling, "How to Publish Christian Books." Here's the promo video. There are two parts to this venture. First, there is the course/series of videos telling how to do it, sharing the insights I've learned from all these years. I'll be sharing these on Patreon until the Udemy course is ready. They will be available under a new tier of subscribers there with one video coming out a week. Tomorrow's video will be on choosing a book size.
However, I'm also offering to publish your book for you. For $100 for each 100 pages, I will edit and make suggestions on content. Then I will make it available on Amazon, Kindle, Audible, and other e-book formats (as you wish, paperback and/or hardback). From then on, I only ask 10% of the net profit.
Since this is a side hustle, I can't take on a lot of book projects, but I can start if you are interested in the conversation.
