1001 web and tech

I am a 16 year old boy and I am in year 11 in a school in NSW, I want to earn money, my parents are not allowing me to work outside due to some personal reasons, I want to work from home or something like that, I can sit on the computer and do something to earn money for around 1 hour a day, I tried eBay but I wasn’t too happy because I was hardly earning anything and I was doing too much work for it, I don’t know if I was doing it the right way. I don’t mind doing jobs like completing surveys or something easy like that, I don’t want to do a job for which I earn under 100 dollars a month, I need to do something because the financial conditions in my family aren’t too good, I am good at computers, I don’t mind learning something new, but I don’t want to pay for something to earn money, I heard about stuffing envelopes, Mary Kay, freelance, web designing, eBay and writing but I don’t really know what this stuff is so if anyone knows what it is please tell me about it. I would prefer being helped by someone who is already doing it and know about it so that they can help me at the start. Thanks I had a look at some other stuff but it was mostly from america so it said that it was'nt available in my area.
