Need extra money, but don’t have much time? There are a handful of side hustles that you can do in just one hour a day. And while working an extra 7 hours per week is unlikely to make you rich, the side hustles listed below could easily pay you $15 to 20 each day, or $100 -$140 per week.

Walk dogs

Instead of going out to lunch, Kelsea Gaspari uses her lunch hour to walk dogs for Wag and Rover. Both apps pay about $12 per half-hour walk and $18 per hour, after site fees, for walking one dog. If you walk two dogs, you get $15 per half hour; $21 per hour. However, many dog owners also tip, so it’s easy to make $20 in a lunch hour.

Of the two sites, Wag tends to have more dog-walking jobs. But Rover is the better site if you can watch dogs overnight —  a side hustle that typically pays $25 to $50 per night.

Charge scooters

If you live in a college town or major city, the streets are likely to be littered with electric scooters that you can rent for a few bucks a ride. However, those scooters need to be charged every single night. Thus scooter companies, such as Bird and Lime, pay side hustlers between $5 and $20 per scooter to take them home, plug it in, and re-“nest” them to set locations in the morning.

What explains the big difference in pay? How tough the scooters are to find. Scooters that are easily spotted are worth $5 to $7 per charge. Elusive scooters that may be holed up in someone’s garage or in a remote location pay up to $20 to the freelancer who tracks it down and charges it.

You need a special charger to start. Bird and Lime typically send up to 10 chargers per freelancer. So you can make up to $50 – $70 per night for charging those easy-to-find machines. Assuming you have enough electrical outlets in your home, you can charge for both companies, potentially doubling your pay.

Since the time required for the job is really just the few minutes required to find, pick up, plug in and drop off the machines the next morning, charging work is easy to accomplish in an hour or two, depending on how many scooters you charge.

Manage social media

American businesses are increasingly turning to social media to market their wares. However, managing social media profiles can be a lot of work, especially for small businesses that don’t have specialists to do it for them. Enter “virtual assistants.” Technically VAs can do almost anything, from helping schedule meetings and travel to updating websites. However, one of the most common tasks assigned to virtual assistants is social media management.

Social media VAs design a company’s social media plan, and can implement it, spending anywhere from a few minutes to a few hours every day posting updates on Facebook, Instagram, SnapChat, LinkedIn, Twitter and other platforms. Where do these VAs advertise their availability? Often on Facebook, Instagram and other social media platforms.

Experienced VAs typically charge between $25 and $75 per hour. However, there are also a number of agencies, including Belay and WorldWide101 that will find VA positions for you, but these options typically pay somewhat less.

Drive kids home from school

If you have a decent car and some experience with kids, you may be able to sign up with one of several online platforms that specialize in picking up kids from school and driving them home or to after-school activities. RideZum, Kango and HopSkipDrive pay between $20 and $35 per hour. However, you do have to cover your own gasoline, insurance and auto maintenance expenses. Still, if you’re in the right neighborhood and have time during the afternoon dismissal hour, its a pretty easy way to make a few bucks.

Teach music

If you have musical talent and think you could teach others to, say, play the trumpet or guitar, you may want to sign up with TakeLessons and LessonFace. While both sites allow you to set your own rates, they’ll take a portion of your pay in return for allowing you to advertise your availability on their sites. Take Lessons charges more, but allows you to teach a wider array of topics, including language and art. LessonFace, meanwhile, has a nice technological interface that allows you to teach online, eliminating the time and expense of commuting to students.

Tutor

If you are skilled in anything from alegebra to Spanish, you could earn $15 to $50 per hour tutoring students through Wyzant, VarsityTutors or Chelsea International Education. The pay is best at Chelsea International Education, but the site has more stringent requirements, too. Specifically, Chelsea favors working teachers, who have been life-screened and thoroughly background checked.
