And while you’ve probably heard of selling sperm or eggs, don’t get your hopes up: Yes, the young and the healthy can sometimes earn good money as sperm or egg donors, but such opportunities require extensive screenings and long-term commitments. Donating blood (sans plasma), meanwhile, is a great and altruistic thing to do, but you generally won’t get money for it.

When I started my first online business back in 2008 (GreenExamAcademy.com, formerly IntheLEED.com), the idea was to help aspiring architects pass the LEED certification exam. I hardly spent any money at all. All I did was start a blog, which at the time cost $6.95 per month for webhosting, and I used Bluehost. (As most of you know, I’m a big fan of Bluehost. And, because I have an affiliate relationship with them, you can get your business website going for much less than where I began, starting at only $2.75 per month!) [Full Disclosure: As an affiliate, I receive compensation if you purchase through this link.]
Naturally, the next one on the list is coaching people how to deliver great speeches. Public speaking is the number one fear on most people’s list – some fear it more than death! This skill can prove to be handy in many areas – from pitching to investors, to delivering key messages at global conferences. If you’re a natural on stage, help entrepreneurs rediscover their in-born ability to communicate by selling effective presentation templates and online coaching classes. 
17. Amazon – Have you heard of FBA? It stands for “Fulfilled by Amazon” and it’s getting pretty popular. Basically, you buy products (in bulk is best) and ship them to Amazon for them to store. When your products sell, Amazon packs them up, ships them out and sends you the money (after taking their cut). There are people making a full-time living from FBA, while others just do it for some extra money.
But, as I said, development costs money. For the Smart Podcast Player, it’s a plugin so it requires constant validation, testing, upgrades, and a solid customer support system in place, all of which costs money. If you have a plan to do something similar for your online business, you’ll need to think about this before you even get started so your processes are covered. Read about the lessons we learned in building the player and how we validated it before launch.
Look, I know it’s not always realistic to pull these off; I personally wouldn’t bother trying. But if you’ve got a ton of stuff lying around — not outright junk, but stuff you don’t need, like the aforementioned DVDs and kid’s clothes — it’s worth a try. Advertise on Craigslist and put up signs in your neighborhood, then come Saturday haul a table out to your driveway (assuming you have a driveway), load it up with stuff for sale, and take whatever you can get.
Basically, you pick a profitable niche for your online business, and then you find an affiliate partner who has products available in that niche. Some of the most popular affiliate sites are Clickbank.com, Amazon.com, and CJ Affiliate by Conversant (formerly Commission Junction). Between them, they offer just about any digital information product (like ebooks, audio files, video files) or physical product you can think of.
18. CraigsList – Some things don’t ship very well. Other things may make you feel uncomfortable to sell to someone across the country. Anytime you’re selling a large item or something you just don’t want to ship, Craigslist is a great place to go. It’s simple to list your item (again, take good pictures!). If you don’t like the idea of putting your phone number out there, the interested individual can send you a message to your inbox without even getting your email address.
What It Is: Students in countries including Japan, Korea, France and Germany are looking for English speakers to practice with. Sessions focus on things like making professional small talk or running a meeting (trainers are provided with specifics on how to teach each topic, and are also trained themselves for two days before starting the job). Lessons take place either over the phone or on a live Internet video service like Skype—sometimes at night, because you're working with students in different time zones. You need to commit to a minimum of 20 hours a week at consistent times, and can work as many as 35 hours.
Consider day labor. You can post an ad online or on a bulletin board offering to do odd jobs. In addition, there are employment agencies that specialize in temporary work. An alternative way to find day labor is to go where other day laborers meet, if you know of any, and wait for employers (building contractors, landscapers, home owners and small business owners). Common odd jobs people need day laborers for include:[21][22][23]

Double check yourself, before you double wreck yourself. Make sure everything you send to a company, whether a résumé, an email or a portfolio, is good to go. Double check your grammar and wording, and for God’s sake use spell check! This is especially important when it comes to the company’s name. Don’t spell their name wrong and be sure to type it how they type it (e.g. Problogger, not Pro Blogger).
The stock market is the type of market in which shares of companies are issued and traded between buyers and sellers. A new trend in this area is ‘social trading’, which is a way of incorporating a social element into investing. It could also be described an online trading social network for traders. One site offering this type of trading is EToro, which brings together a community of traders who copy each other’s investment decisions to earn money. If you are looking for a more traditional approach, then companies such as Options House may be an option for you. In case you already have some experience in trading, you may be interested in such types of trading as Forex.
While this is not technically “at home,” you can still earn great money without ever getting on the phone using your personal car, bike, or scooter to deliver food, give people rides, and even picking up groceries. The great thing about these companies is that it's also very flexible work. No one is telling you when to start and stop. You just do as much work as you can, when you can.
