Cooking Classes???

My wife Erica was talking to me the other night and asked if I still wanted to teach. I love food so much and cooking and sharing knowledge, I of course said yes. We thought I should do some private cooking classes for people at their homes. I am working on the structuring of lessons and costing out everything I will need to get started to make this a reality. I think it is something I would enjoy a whole lot and it could help me financially. If anyone has any ideas on lessons, let me know.
