Yeah Katie as blondie says its not that easy.
I was out there from April to October last year...loved it!!
Although i didnt work...it is hard to get a work permit there,i have known of people to work in bars etc,but this isnt always a safe option if you get caught. Know of a few people that were deported last summer.
My advice would just be to save as much as you can if your planning to go for that long as just enjoy it!
I did!!
