There’s an excellent chance that you have one or several musical instruments sitting in storage that haven’t been used in years. Perhaps it’s a leftover from when you were in school, or even from your days playing in a band. Whatever the reason that you have it, it’s probably worth money if you can sell it. Brand-new instruments are ridiculously expensive, so people often look to buy used equipment instead, particularly if they are novices.
Pro tip for first-timers: Carefully consider the pay rates that are listed. Penny Hoarder Carson Kohler has used the platform to find freelance writing gigs, and she reports low rates — like $3 for 500 written words. It’s probably not worth it. (And, yes, you’ll have to scroll through a whole lot of these low-paying listings to find the good ones.)
Find a profitable niche. Starting with your interests, write down as many niche ideas as you can. Think about topics people might search online. Ideas include passions (like surfing or body building), fears (like spiders or speaking in front of crowds) and problems (like getting out of debt). Do keyword research to see it others are interested in the topic. Find out if a domain name is available that matches the keyword 100 percent. 
Alibaba is a Chinese eCommerce store that matches Chinese suppliers with buyers all over the world. Prices are extremely cheap, providing the possibility of large profits. However, with the potential profits comes more risk. As you are dealing with suppliers in China, if the quality of the product that arrives isn’t up to standard there is little that you can do about it.
My real job does not pay enough. I do surveys online all the time and I am always looking for more ways to make money online. I would love to work from home full time but I honestly don’t see it happening. I am already a member of the survey sites mentioned here. But the truth is you are usually going to make closer to 30 cents to maybe 75 cents per survey. I hate seeing claims that you make $5 to as much as $75 per survey and for minutes of your time. Most surveys take 30 minutes or longer. Pay closer to 75 cents (that is 3 quarters) and there are lots of times you finish the survey and don’t even get paid. Anyone who has done the survey thing for very long knows this is true.
Amazon and Google are far from your only options for online advertising. Rakuten Linkshare is a great place to search for other affiliates for your ads. Through their program, you can get customized ad links, email links, and banner ads for Starbucks, Walmart, iTunes, and a slew of other popular brands. With this program, you can also find smaller companies, regional or specialized brands, and more. I run a combination of Google, Amazon, and Rakuten’s programs, and my monthly income is approximately $150 from these programs. It’s not a lot of money, but it’s also not a lot of work for residual (it means recurring…since the ads are permanent…) income.
Learn then selling guidelines. Each marketplace has guidelines that define what you can and cannot sell. State and federal laws also impact what items are prohibited. In general, you cannot sell alcohol, weapons, service contracts, animals or event tickets. Also, while not always prohibited, you may find restrictions on how you can sell items in some categories, such as art, gift cards and coupons. eBay, Craigslist and Amazon publish these guidelines on their websites.
Where Indeed excels at finding job postings across the web and acting as a search crawler for employment, maybe a full-fledged career is too big of a commitment at this point in your life. Elance is a site to find freelance work of all types. I’ve used it for quick writing, editing, copywriting, resume building, and other odd jobs and temp gigs. The experience has been great.
