you're not aiming too high, you must have not seen the movie Wall Street

somebody already suggested fiverr, well it's actually one of the easiest formula, it's very hot now and it's growing day by day
post 20 gigs on fiverr, you said you already have some tools, generate 25 sales/month (highly possible with 20 gigs) which is a little less than 1 per day and you're already there, actually it'll be $99 after paypal takes their cut and you don't have to work 15 hours per day, only a few minutes at most
there are a lot of threads here with great tips about fiverr and WSOs in the dl section, study them, you don't have to invent anything, you don't really need to be creative (it's not a problem of course if you are), see what works, what not, which the most popular services are, just go with the flow and you may end up making more/much more than $100 month
buying traffic is already there, you "just" need to leverage it
