Without knowing your exact situation, it seems like unless you want to do this long term, the startup cost for a legitimate lawn cutting business (truck, trailer, mowers, etc.) would be prohibitively high, and the type of lawn cutting "business" I had when I was 14 or 15 where you just mow a few neighbors or family friends lawns wouldn't earn you very much money. Since the title of your post is summer job options, let me tell you about some summer jobs I've had that you might consider. The best summer job I've had as far as money and hours was as summer help for a mechanical contractor. I got over ten dollars an hour an hour and worked a normal 7-3:30 monday through friday schedule driving materials and tools from the shop to job sites and doing some pre-fab work. It was a good job and I usually found it relatively enjoyable. I loved the hours and the pay and I met some interesting characters, but I only did it for a year. For the past 3 summers, I've worked as a counselor and climbing wall instructor at a summer camp for kids with special needs, and I absolutely love it. The hours are much longer than the summer help job I had and the pay isn't as nearly as good, especially if you calculate my weekly salary into an hourly rate, but its a ton of fun and one of the most intrinsically rewarding things I have ever done. Also, although I don't make as much money, I also spend a lot less because I live at work and meals are provided. Another job I had before the summer help mechanical contractor job was as kitchen staff at a summer camp. I did a little bit of everything, from prep and service to scrubbing pots and pans. This was another fun job with a normal workweek, although the pay wasn't as good as the summer help job.
