Fun question?
 

If you wanted to make $50 per day what would you do? Let's exclude poker.

Hmm, the first two things that come to mind are:
1) Work a low-paying job
2) Maybe start a small website

Is the question geared more towards "if you only wanted to make $50/day" or are you asking "if you wanted to make an additional $50/day"?

Make an additional $50 per day. Let's see if we could get some passive income.

Are you allowed to invest any money? How much?

Setting up a website for affiliate sales where you drive traffic with cheap advertising seems to fit your requirements with a low startup cost and low time requirement once set up.

Another idea is to employee some low cost high skill labor from the Philippines or India (they speak english) and use them to do contract work that you acquire here. You'll need several people to make $50/day.
