I've been thinking of developing a way for homeowners to hire the local teenagers and children to do small jobs like lawn mowing, babysitting, dog walking and housesitting etc. A lot of people like to hire local kids, but don't know enough people in the neighborhood, and don't have time to search. It would be a way to strengthen community ties, and foster teen work ethic as well as give them an opportunity to get a start on financial planning and budgeting.
It would just be a way for them to get in touch, and help choose someone reliable. I still don't know how to avoid untrustworthy people preying on children, and I do not know how this would work with child labor laws. As far as I know though, teens have been hired for this kind of work for years without any problems.
