My first job as a teenager was IT for a babysitting agency run by my school. They employed former students as the babysitters. It was very popular but when they tried to scale it beyond the school it failed. Basically parents were willing to trust that the school knew its former students, but not willing to trust people recruited any other way. Personally I would use such a service, but you'll have to work damn hard to show you've vetted people carefully.
