Over 200 ways you can make extra money in your spare time

Call it the sharing economy, call it peer-to-peer commerce, call it collaborative consumption, but no matter what you call it, it's having a massive impact on how we do business and disrupting established industries at a breakneck pace.

I'm talking about the renaissance of people doing business with people — instead of giant companies — a movement facilitated by an ever-growing array of marketplaces and apps.

If we think back in time 200 years, almost all commerce was peer-to-peer, right? We traded in small town squares and knew our neighbors. Then big corporations came in and took over the world.

The "sharing economy" — with the help of websites and apps — is displacing some of those corporations and getting us back to our roots. The premise is we have underutilized assets in our lives, and we can sell or rent those assets to our neighbors in win-win transactions.

Want your piece of the pie? Here's how you can get in on the action.

1. Share your art

Creative Market: Sell your designs, website themes, fonts, photography and more on CreativeMarket.com.

TurningArt: TurningArt is a unique art rental marketplace for homeowners and workplaces. Artists earn royalties each time their work is rented, or when prints or originals are sold through the site.

Minted: Minted offers wedding invitations, stationery, home decor and other items from independent artists and photographers like you. Earn cash prizes for one-off contests and commission on on-going sales of your work.

Redbubble: Join the network of more than 350,000 independent artists selling their creative work on Redbubble. You have control over the price of your work, with most artists earning 10 to 30 percent of the retail price.

Cafepress | Zazzle: These are a couple of the largest print-on-demand t-shirt and other merchandise sellers: Cafepress and Zazzle. How it works is you upload your designs and create your own storefront. When someone buys, you earn a royalty on the sale, but never have to touch the inventory or ship the product; the company does it all for you. I think this has the potential to be a really cool passive income stream, especially if your designs can begin ranking on their own in Google.

Teespring: With Teespring, you create your own unique t-shirt designs and then market them to relevant audiences, earning the spread between your purchase price and the cost to produce. The interesting thing about Teespring is unless your campaign hits a minimum critical mass of orders (that you set), nothing gets printed and nobody gets charged.

Threadless: Create your own store and submit your t-shirt designs to a fun community of independent artists and fans. Like other print-on-demand clothing sites, Threadless allows you to make the spread between the purchase price and the cost, usually around $10 a shirt.

2. Share your boat

Boatbound: How often do you really get out on the water? With Boatbound.co you can rent your boat to you landlocked peers. A quick search of boats nearby yielded plenty of results with rates ranging from $300 to $2500 per day.

GetMyBoat: GetMyBoat.com is another peer-to-peer boat rental platform with listings all around the world.

Tubbber: You can find peer-to-peer boat rentals, primarily in Europe at Tubbber.com.

3. Share your car

Uber: Uber is the proverbial 800 pound gorilla of the sharing economy. Their ride-sharing platform offers the opportunity to essentially start your own taxi service and earn money on your own schedule driving your neighbors around.

Lyft: If your car qualifies for Uber, you might as well join Lyft too. This ride-sharing service is branded more as "your friend with a car," perhaps a little more personable than the Uber behemoth. Because of that, I actually prefer Lyft as a rider.

Turo: Turo is a leader in the peer-to-peer car rental space. If driving people around Uber-style isn't your jam, you might consider this as an alternative. Your car probably sits idle at least some of the time and the idea behind Turo is to put that idle time to use by letting someone else use it. They've even got a cool little calculator on their site to estimate how much you might earn. Naturally, the nicer and newer cars in popular travel destinations earn the most, and I've actually heard of people taking out leases on cars specifically to rent them out on Turo.

DropTrip: This platform matches travelers with people who need stuff shipped. Got extra room in your trunk? Offset the cost of your trip by delivering something that's heading the same direction using DropTrip.

Wrapify: When you sign up with Wrapify, your car gets covered with a giant advertisement and you earn money based on how far you drive. A typical commuter in a popular area could earn $50 to $100 a week.
