Summer Programs/Internships 2017?

I’ve been looking for relatively shorter summer programs/internships for the summer of 2017. I’m mainly interested in business and comp science/engineering, but I don’t want to spend 4+ weeks on a program or internship that works daily since I have other commitments. I’ve also noticed that many programs seem prestigious but really aren’t since they almost accept all students as long as they are able to pay a huge load of money.

Are there any programs/internships that you know of that is fit for a high schooler like me?

Thank you in advance.
