Anyone in the neighborhood have a reliable teen who mows lawns? Seems like looking at Craigslist, people want $20, 30, and up for a regular sized typical mowing job that would take a kid with a mower under half a hour. We'd love to find someone who would do it every week or two for $15, which feels fair, especially for a kid wanting extra summer money as opposed to a "lawn service" adult. Any recommendations?
