Another unexpected opportunity

A family friend has a son who teaches the special education class in the elementary school down the street. What an opportunity! I realize that he can't just promote me through the school but I'm sure he's got enough clout to connect me with others who can help and/or tell a few of his kid's parents about my desire to work with a few of them over the summer. Skills programs vs. babysitter- which is better? Now I don't have to pay to advertise, I'll already have someone to help.
