I would suggest that you and your parents reach out to business people they know to see if anyone would be willing to have you at their business in the summer. Personal connections are probably the best way to get something for a 16-17 year old.
My husbands office hires (yes they pay) summer high school interns, but really they don’t do much except act as gophers, do copying, run things from one side of the office to the other, etc. Still it’s a chance to see how their business runs. In their office, none of these are full time.
