free2beme: LOL. Most of these are more difficult than you might think! Prostitution: the prices resemble the markets, here in Europe they are down, down, down, because any "neighborhood girl" is now into this (google Greece, Spain or Portugal & Prostitution!). This is a service market that responds to supply and demand. And right now the supply is over the top, hence drop of prices. The same goes for drugs. I meet a drug seller the other day (street seller) and he said he will go back to selling newspapers because there is so much competition and the demand is down (this is Europe, some countries have legalized drug consumption if it is for your own use).
Here is what has worked for me - no affiliation or anything. I gave this link to a couple of people and so far they are extremely happy. Some have started with as little as 50 US$.
www.etoro.com > Trading meets Social networking. You deposit money. Copy the most successful traders and they trade your account for you. There are security features to limit the risk. Very easy to use. Platform is really for "dummies". You can chat and talk in real time with the traders and learn why and how they trade. Really neat. You can also trade with "monopoly money" to test it out. Once you're there check out this guy: caraj51 (you can search for him). He is top notch, makes me in average 5 US$ per day on a 100 US$ account. Some days nothing, others more, but pretty reliable.
I've tried freelance jobs on Guru.com, but you are being hit by the globalization and the crisis everywhere (competing with guys from Bangladesh and India that know tons of programming languages for 1-3 US$ per hour. Not funny. Unless you want to hire people there and resell their jobs for a higher price in the US. That is something that I will look into. Opening a service office, get jobs from small to mid-size companies and hire your team on sites like Guru.com / elance.com / oDesk.com etc.)
Hope this helps. I use etoro myself, but always looking for more opportunities (my account there is too small yet). Wish you good luck. We will need it...
