Work in Europe for a Student:)

Hello,

I'm new to this site and kind of unsure on how it all works but i have some questions. Currently I'm a student in Canada and looking into spending 4 months ( may-aug) in Europe. The thing is, i would love to just go to be a tourist but i need to make money while im there because of the fact that im a starving student. If anyone could give me some advice for where the best place would be to find work or what type of work i should look into that would be awesome. My wish list of places to go is either Italy, Greece, Spain and Switzerland..but i would pretty much go anywhere:)

thanks so much, any advice will help!
