Maybe you're a teacher, with a couple months of downtime before the new school year in the fall. Or a student, hoping to pocket some summer spending money or get a jump-start on your retirement savings. Or, heck, just a hard-working 9-to-5er trying to fund an overdue beach trip or looming holiday gifts. You want extra cash, and you want it now.

Consider these legitimate moneymaking opportunities that you can get started with right away. Some require skill; others only demand time and effort. Our list includes resources and tips to help you get started earning extra money. Take a look.

Get Paid for Your Opinions

Market-research firms are hired by big businesses to get inside the heads of consumers. Participation in an in-person focus group led by a moderator, such as those run by Focus Pointe Global, can earn you between $65 and $200. Focus Pointe Global also has opportunities for telephone or online surveys.

In exchange for taking online and phone surveys, firms such as Harris Interactive and Schlesinger Associates offer rewards points redeemable for gift cards and merchandise. Beware scams, though. Legitimate firms won't charge a fee or ask you to cash a check and wire back part of the money.

Lawyers are getting in on the act, too. "Online jurors" can earn cash for giving their opinions on legal cases. EJury.com pays $5 to $10 per case. You'll need a PayPal account. At OnlineVerdict.com, where fees range from $20 to $60, payment is made by check.

Be a Tour Guide

If you know a lot about the city where you live, you may be able to profit from your knowledge by guiding tours. For example, travel guide sites including Vayable let anyone list a tour or experience that tells a unique story about a destination - from its art to its history to its food -- and earn money from bookings. U.S. tours that are promoted on Vayable -- such as a San Francisco street-art tour or a Washington, D.C., White House tour led by a member of the White House press corps -- range in price from about $25 per person to $200 per person, though more-upscale experiences are priced even higher. Vayable takes a 15% cut of whatever you choose to charge travelers and provides online tools to manage reservations, accept credit-card payments and securely communicate with customers.

Are you a runner? Consider earning extra bucks as a running tour guide. City Running Tours - "sweat and sightsee simultaneously" - is one company offering "sightrunning" (it's a thing) services in 13 (and counting) U.S. cities, including Washington, D.C., and Honolulu. The company offers personalized or group tours. Tips aren't required, but permitted.

"Our tour guides make on average about $20-$25 per tour plus incentives based on seniority, type of tour, distance, number of participants, referrals and positive reviews," Michael Gazaleh, president and CEO of City Running Tours, tells Kiplinger.

Tutor

If you have a special skill -- whether it's the ability to play an instrument well, paint like Picasso or explain calculus in a way anyone can understand -- you may be able to make money sharing it with others. For example, you could earn $15 to $60 an hour tutoring individual kids or college-bound students if you speak a second language or have great math, science or writing skills.

Advertise your services on school, campus and community bulletin boards, or tutoring web sites such as Wyzant and Tutor.com. And take advantage of social media sites, such as Facebook, to let people know about the lessons you're able to teach.

Join a Street Team

Street teams need energetic, outgoing helpers to promote products, summer blockbusters, albums, events and more by handing out samples, interacting with people on the street, or dressing as mascots. To get a job earning $20 to $25 an hour, sign up with a company such as Street Team Promotion, which handles promotions in big cities nationwide. Make sure you get a contract that specifies when you'll get paid.

Be a Babysitter

Babysitting can be a fun way to put money in your pocket if you like kids. In big cities such as New York and Washington, expect to earn up to $20 an hour as a babysitter or nanny. (In small and midsize cities, the going rate is closer to $7 to $10 an hour.) Advertise your services on community bulletin boards, the public library or houses of worship. You can also place a listing or search for jobs on sites such as Care.com and Sittercity.

Walk Dogs

Get a little exercise while you earn anywhere from $15 to $30 an hour. Working folks will pay plenty for you to take Rover or Scruffy on a daily stroll while they're at the office. Or consider pet-sitting for people while they're on vacation for a daily fee of $50 or more. Advertise your services in veterinarians' offices, on Craigslist or on sites such as Care.com.

You can also team up with an existing dog-walking operation that handles client recruitment and scheduling. To find one, ask other dog walkers you encounter whether they're part of a group, or check Craigslist.

Profit From Your Garden

If you grow your own vegetables or raise chickens in your backyard, you might have an overabundance of produce or eggs that you hate to see go to waste. So profit from it, instead. Kiplinger's office manager, Glen Mayers, sells eggs from his 12 hens to colleagues for $3 a dozen, on Craigslist for $4 and at a farmer's market for $5. He also sells honey from his bees for $9 per 1-pound jar. He puts the cash he earns in a jar at home, and his family uses it for fun outings together.

Rent Out Your Home

Looking to fund your beach getaway by renting our your city home while you're away? Websites including Airbnb make it easy to rent out a spare room, a wing of your house or a backyard cottage.

Beth Everett and her husband, Glenn, built a cottage in their backyard in 2014 for their son Jordan to live in when he's home from college. But while the studio sits empty, visitors to Portland, Ore., can rent the cozy space through Airbnb for $75 a night.

Fox Lair, as it's known, offers heated floors, a small sitting area decked out with guitars and bongos, and plenty of eclectic artwork. Everett estimates that in 2015 they earned about $9,000 from a steady stream of visitors, money she used to help pay for editing and cover designs for her self-published books, the Lee Harding mystery series. "It was the easiest money I ever made," she says. "And it was fun."

You can list your space free on Airbnb, then pay 3% to the site when you receive successful booking. (Airbnb will reimburse you up to $1 million for damage to your property.)

Drive Other People

If you've ever found yourself in need of a quick ride, you may have turned to Uber, the anytime, anywhere ride service that has gained popularity over the last several years. But have you ever considered becoming an Uber driver? If you are at least 21 years old, own a car made after 2000 or 2005 (depending on the city), and pass background and driving checks, you could earn cash by driving people around in your free time. According to Uber, drivers' average earnings per hour are about $19. But don't forget to factor in the costs associated with using your own car, such as gas, maintenance, insurance and cleaning.

Uber's competitor Lyft says its drivers earn up to $35 per hour. Like Uber, Lyft has age, vehicle and background-check requirements for drivers.
