Startup Idea : internship opportunities for teenagers

I have tried googling up internship opportunities for teens lately, but the search results have not been successful. As a student enrolling in highschool I still have no idea what career I would like to pursue in the future! If i was given internship opportunities to explore and experiment with different fields it would greatly help with choosing my career. I was thinking of a website which a student would log in and search up internship opportunities present in their city. Based on their interest the website would direct the teen to a list of search results. The application would be listed for various internship opportunities and the employer would pick select candidates that would benifit most from the internship through their resume and cover letter.
