Other than that, if you are willing to move out of the internet, you can always make websites (or even apps) as a free lancer, those will mostly pay you quite a decent amount.
Web dev is the worst paying field ...
You get to compete with India and China, who charge $400 - $1,000 USD a month for work .
Most local shops, caffes and service providers won't hire someone from China or India to made their small site.
I have many friends that would make quite a bit of money (for a student) during college from those freelances, at least in my country, it pays a lot more than most internships. Of course, you can't hope to provide for a family with this, but you can surely make enough money to pay for student's needs (which are likely to be food, parties and drinks).
