Rose and others looking for employment this summer: Retry the babysitting idea. Summer is a good time to babysit. Maybe volunteer a few times first and then use those families as references. Tell everyone you know that you are available to babysit. Use email, Facebook, fliers, word of mouth. Also try offering a set time every week, like Tuesday evenings form 5-9 pm in your home. Parents know they can drop off their children without calling ahead. They really appreciate that. It takes time and persistence to get the word out, butit can be done!
Websites like Care.com connect parents with babysitters. The company does all the background checking and other due diligence to put parents' minds at ease. Of course, you can appeal directly to people in your personal network, but if you're looking to generate recurring revenue sign up with a site marketing to parents looking for child care services.
