I have been trying to make a post in this very helpful website, but may times unsuccessful. Fortunately, this computer's server finally allowed me to do so

Well, there were many previous posts of this sort, but I think each one's concern is unique.
To introduce myself, I am Eugene John Balmores, a Filipino. With luck, I was accepted to the International Master's Degree Program in Neuroscience (MNEURO) at the University of Helsinki. I really want to pursue the degree in Finland. That's why I have been searching the internet, looking for helpful sites and information. I already know a little of the people, climate (very cold?), and high regard to Finnish education. I also know of the requirements for the student residence permit, and I am currently fixing them.
My main concern at the moment is that my family's resources may not be enough to finance my living expenses (from the previous posts, this indeed is a major problem). I understand that one can be employed part-time during the semester, even summer, but looking for a job is very hard. But I guess, this won't dishearthen me and stop trying.
My plan is to apply, say to a cleaning company or english day care center, before filing my student permit application. I am hoping to declare the earnings which I will be getting from the job as part of my funds to finance my studies (besides the 6000euro in my bank account, which I am struggling to raise). Is this plan allowed at all? Or will there be problem/confusion on whether I should apply for working or studying permit?
With regard to the plan above, IF it is indeed allowed to secure a part-time employment prior to student permit application, do you guys know of companies who directly hire people from abroad? I searched for cleaning companies (ISS, SOL, L&T) but aside from unavailability of pages in English (very hard to translate each Finnish word, one at a time), I think that it will be hard to get in if I don't know someone (or if you can refer me, that will be nice

Any help from you guys will be MUCH appreciated! Options, comments, reactions are very welcome.
Thanks very much!
Lämpimin terveisin,
Eugene
