Maybe audit a cyber security course for free on coursera? This one just started January 18th:

You could also maybe try building custom pcs for people to make a bit of money.
A good thing about this is that you can do it in college as well without necessarily taking too much time away from your course work, so it could be worth it to get started on setting up shop now.
