How could I make money by hitch hiking across the country?

I recently left my job and don’t want to just jump into something else. I want to be open to where I will be the most fulfilled and also the place that I can most add to the world. I want to do something to help change the world for the better. But I worked at school for troubled kids so don’t have tons of dough in the bank. Any ideas on how to make money on the road? I know blogging and I photograph so I could set up a website and sell photographs but I need something to make like 50$ a week. I want to think of something no one else has. Any ideas?
