Your only way to make money would be online because you are in a remote place with no phone, no people to talk to, nothing... just a PC and internet connection.
You need to make at least $50 so you can buy a service that will save your life... The only condition is: you cannot ask people to give/lend you the money, you need to earn it. You're just a normal PC user but not an internet marketer so you don't have list, website or such.
Oh, and you can invest let's say $25 to make it work... as long as your net profit is at least $50.
What would you do?
P.S. Based on some responses I'd like to add that by no means is this a question based on a real need LOL, I just want to get your fantasy going and am curious what you can come up with.
