EDIT: Meh, I'll contribute to this topic in fact.
I once had the same idea of making money online, so i did my homework and all. Basically, all of your early earnings aren't going to be sufficient. Your material depends greatly on time. For instance, you start with new account (any where on the internet where you can earn money) and you basically offer your services or entertainment or whatever business you're in. Your income will depend on your audience and loyal customers, and these two take time to acquire.
Freelancing isn't something you built in a month or two, you need to expect - for at least a year - to have low to average income with constant effort on your end, since you need to build suitable infrastructure before you can start earning decent money.
Not to put you down or anything, but don't waste your time on this sort of thing if you're only planning on doing it temporarily, you won't earn anything worth your time.
Just borrow some cash from a friend or family and pay it back once you get another job. Or use whatever savings you might have more wisely so you don't run out of money.
