The studies might be one thing, but whatever part time work you find - if you find one, will not pay your studies.. There is a huge unemployment here, and to have a chance to get a work at all ( with a low salary as Ken wrote ) you would need to have experience, i.e being better on something than everybody else, speak Spanish, and last - but not least - have a contact net with friends that can find a work by their friends, realitives etc..
If you dont need the money, but just looking for the adventure and an experience you might have the time of your life, if you need the money of a job to pay for education - then forget it.
