Hi, my name is Elio.
I've been using LaTeX for more than 15 years.
If you send me one of your tutorial and the exact template you want to use, I can make one example file with all the instruction to easily convert all the rest of your tutorials into the LaTeX code.
Once I know the template and the source, do it, and tell you how to do it, it is quite simple.
Let me know,
Elio
