On a serious note, there's no such thing as a papal monkey/paypal money/btc generator. This is an old joke. So, if you are serious about it; then think about your options again.
P.S. You can easily get the money back (and make much more) with the features you will get by upgrading. The easiest way is your signature space, which you can rent out as an upgraded member. Not to mention the capability of being able to respond in Hire a Freelancer and Want to Buy sections. That's the real money generator.
