There are some excellent methods here on the forum for making a lot of money in a relatively short amount of time, but I can guarantee you that if someone DOES have a SURE-FIRE method for making $1600 in three weeks, they won't be revealing it on this thread, or anywhere else on the forum.
Read the money making threads on the forum. Check out Harr0's money-making sticky, or some of Nick Flame's stuff and other great members' posts of money making ideas. Then create a new "twist" on some of those ideas.
Often, many of us receive PM's from people with unrealistic expectations, whose question usually goes, "Can you show me a way to make $1000 dollars by next weekend?" They are under the false impression that we all have a one-paragraph, sure-fire method that we can give them, so that they can leap over all of the tactics and ebooks and get rich in a week. Contrary to the hype you may be reading on sales pages throughout the internet, internet marketing takes a lot of work and a reasonable amount of time through trial and error before you start to see some substantial money. And every once in awhile, after all of this trial and error, we stumble upon a great method. But most of us are smart enough not to give it away, because we know that once that method becomes "forum knowledge" it will immediately become saturated and as a result, lose its effectiveness.
Read the posts and start thinking "out-of-the-box" and eventually you will also hit on a great idea . . . and if it is something that can become quicly saturated, keep it to yourself, or at least write a great ebook about it and make a quick killing on Clickbank.
That's my take on it . . .
