The easy way to start making a few hundred a week is go get a job.
As others have already posted, you can check out the making money methods, but if you are new my best advice is to find something that interests you, LEARN it inside and out, and then start trying to make money.
A few hundred per week is not an easy thing to do just starting out, it took me a long, long time to even make my first $1. It was when I decided to just learn a topic first and then find ways to make money with it, that is when the money came.
Just doing a method with no knowledge of what you're doing is a good way to make a few bucks and then you hit a roadblock and have no idea what to do because you don't really understand the concepts.
