I’d also bring my own equipment. If participants are already at work, it may be difficult for them to store or carry the equipment with them. You want to decrease the amount of objections or excuses for why they can’t attend the class. The more things they’re responsible for, the more likely they won’t attend.
I’d also price the class with the considerations of: minimum amount I’d want to make for my time, including travel. Cost to cover materials for the class. What the going class rate is in your area. Etc.
Good luck with the class!
