Spending money on the poor

Q: I want to know about urdu word "nazar e muyyan", people sacrifice animals if they are ill, or calamity stricken and want to get out of difficulties.

Note: This is done without any commitment. There is another type of commitment that if I succeed I will spend such and such on the poor. I am asking about the 1st type. Does it have any relavance. If that is true, can I spend money because I cannot sacrifice an animal because of living in a foreign place?   

Collecting funds for one's education

Q: I wanted to ask about collection of funds for my education. I live in Pakistan, but I am not financially strong. I earn but I am unable to fulfil the family expenses. I want to study further in AUS, that way I can earn in dollars and might be able to pay off loans on my family and expenses. For that, can I collect funds from people? I am unable to save and fulfill family expenses at the same time but I dont want to make money in a haram way nor will I persue this if I am not allowed to in Islam.
