My 10-year-old son brought home a book from our park’s free library box. It was a biology textbook – teachers edition. He said it looked interesting and hey, it was free (having no idea you could sell it). I scanned it in my Amazon seller app and realized it was worth around $150. He was so excited. We listed it for sale for $130 and it sold! Going to tell him, he just made $130!
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.
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).
If you're a crafter, the internet is your showcase — and not only at auction sites like eBay. DeWitt Young of ObviousFront.etsy.com has had success turning her crafts into cash online. She has a booth at Etsy.com's Craft Mall, an amazing place where thousands of artisans and crafters offer their goods for sale. DeWitt turns salvaged parts from old TVs and VCRs into artsy necklaces, earrings, and figures. Colleen Jordan of wearableplanter uses 3D printing to create her necklaces called wearable planters.
Whether it’s an important consumer application, a specialist app to solve a particular niche problem, or even a time-wasting game you can play on your phone, you can create a massively successful business if you build software that helps people. (Look at the rise of Slack—the team communication software that went from side project to billion-dollar company in just 2 years.)

Instead, try scratching for free using an Android app called Lucktastic. (It’s called Lucktastic Match for iOS.) Each day, it releases a new assortment of digital scratch-off tickets. Lucktastic says instant wins range from $1 to $10,000. You can also earn tokens that you can exchange for free gift cards to retailers including Amazon, Walmart, Kohl’s, Sephora and more.
Next, you need to set up and build your YouTube channel. Your YouTube channel is your homebase for all your content. If you already have a Google account for Gmail or Google Drive, then you can use that to log-in to YouTube and start setting up your channel. Pick a username that works for you and is memorable (if you’re using an existing Google account you’ll have to edit your username in Google+).

A blog highlights your technical ability and showcases your ability to write blog posts. Your blog can be about different topics than those you write about for your clients. In fact, it should be on a topic that interests you. Visitors will see that you can not only write, but you can also build an online community. A good blog has the potential to earn you many referrals for more clients.
The second (and cheaper) path assumes that you have the design and dev chops yourself to build your dream software. Naturally, it’ll take more time to get your product off the ground, but being able to bootstrap the development of your software lets you retain more ownership in your business and be more in control of your path, making this a lower-cost, but higher time investment to make money selling apps.
Research. You need to know what others are selling before you decide what wares you will offer. Lots of people sell handmade items, but those who work hard to make their items unique in some way are the ones who truly stand out. After you’ve decided on a product, check out the other sellers on Etsy and find what they’re offering, and then figure out how you can do it differently.
One of the best places to sell unwanted personal possessions is Decluttr, a website that buys used items directly from consumers. Unlike trade-in marketplaces such as Gazelle and auction websites such as eBay, Decluttr doesn’t act as a middleman between buyers and sellers. Rather, it’s best understood as a bulk buyer: an enterprise with deep pockets and an unsatiable appetite for used consumer products.
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. 
You might be desperate for work, but don’t necessarily jump at an opportunity that sounds too good to be true. In my article about common Craigslist scams, I wrote about fake employers who “hire” new employees, then “accidentally” send them too much pay. They’ll ask their victims to wire back the difference, but a few weeks later, when the bank discovers that the initial check is a fraud, the “employee” is on the hook for hundreds, sometimes even thousands of dollars. If a job offer sounds too good to be true, it probably is.
Set up the site. Choose a website building platform, such as WordPress, Joomla or Drupal. Next, choose a domain name and web hosting for your site. The domain name is your web address. Web hosting is a service that connects your site to the internet. Once you have your domain name and web hosting, go to the control panel of your hosting account and install your website platform. Design your website by choosing and installing a theme.
