I did a Stone, Tile & grout cleaning class on DVD. Audio, PowerPoint, manual, quizzes to take, lots of photos and so forth. It sold for $100 for many years.
Decided it was getting old and needed to be up-dated. Took the ads off and had 7 copies left. I will mail a free DVD to you if you send me an email with your shipping address, contact info, company name and such.

if you have an extra left over, I'll thank you for letting me get one, I'm still learning
