If you actually go ahead and work for that type of money then I don't even see it as a high sum of money if you're actually putting in some sort of time and effort into the activity. Though, if you're just going to be dicking around and not putting effort into something expecting to make hundreds of dollars per day then you'll be going through a disgusting reality check with not getting a dime out of it.
People on here want an easy way to make money, and the crazy thing about money is that there really is no EASY way to do that kind of thing. You have to find something you're good at and put it to use for the people in the community here for a price if you want to make something out of it.
Sure you can! That is not impossible. At two months you only need to earn $50 a month which means you just need $12.50 a week. Just earning $2 a day means you can already reach your target $100 and you still have $20 to spare. I would suggest you work for it and not gamble, gambling is easy and quick money, but it is too risky.
Still seems like a small amount of money, what type of work does OP think he's going to be doing?
