There's no race to riches. $2100 over 3 days, 5 days or even 30 days... most people wouldn't mind at all. Just as long as these types of methods really work and can help pay the bills.
My point isn't about how much money he made in 3-5 days. It's about whether these methods actually make money. Be it over a month, 2 months, 3 months, whatever...
I think the OP's ideas are really good and sound. Whether he actually made over $2000 or not is debatable, but that is not really important to me. He gave some really good ideas that I can use.
