Im from bolivia, a future exchange student in ginebra

Hi everyone! Im a female 21y student from bolivia looking forward to go study in Ginebra-Swiss, but I dont know any french, that wouldnt be such a big problem but the real problem is this: the university is free for me because of my schoolarship, but I have to pay my living there, in bolivia theres a big economic problem so it is impossible to send or recieve money and it could be too much expensive (like 13k or 14k per month, with that amount of money i could live more than six months in bolivia) so the only option would be to work part time as a student there in genova italia, any recomendations about rooms, departments, places to work, etc? I would rather not to go if i cannot sustain me while working part time and studying, is it difficult? Or is it difficult to find a job? How is the life cost and the work pay there? Do the works pay well?

(I have 3 options to live and study, italy, swiss or spain, so im asking separately to get info from people who live there)
