Well, this is a business itself, the student can buy something and sell if with a profit margin. The thing can be stationary(books, pen, pencil, notebook etc), which is much required by the students in a hostel or campus; a food item (especially Maggi at 12 am) or some en-clothe and many other things that you might feel required for the vicinity population. This can be a mini business and can earn a good amount if intelligently and thoughtfully persuaded.
You can either organize a yard sale yourself (which is kind of a hassle), or better sell the items through ThredUp, which will pay somewhere around $2-$25 for staff from Gap, Banana Republic, H&M, etc. You can browse around to see how much different items are worth. The best thing about ThredUp is that all you need to do is pack your clothes in a box and then just ship it to them (shipping costs are covered by the company).
Watch for emails asking for note-takers. Once a fellow students' needs are documented, disability services will contact the professors and ask for volunteers in the class to take notes, and your professor will in turn email the class. You can also upload your notes to a platform like Stuvia, where you can earn money by selling your notes to other classmates.
Barter your services with friends. Do you spend more than you'd like getting your hair and nails done each month? Do you have a friend who can't resist the pastries at the coffee shop or who pays for a personal trainer? Think about what both you and your friends spend money on, and then see if there's a way for you to barter and trade services with each other in order to save money.
Have some extra space in your home? Turn that extra bedroom into a “bed and breakfast” room. If you live near any sort of tourist destination, you can try your hand at renting out a room through Airbnb or CouchSurfing.com. You may also find paid hosting opportunities in your community: Sign up to host exchange students, visiting professors to a nearby college, or hospital patients receiving long-term treatment.
As an Uber driver, you can choose your own hours to hit the road and make extra money. So if you want to drive for Uber right after you finish at your 9-5, you can do that. If you want Uber to exclusively be your weekend gig, you can do that too. We like Uber because its easy to get setup and its one of the more flexible money making ideas out there.
Once you decide on a topic or niche, you should sit down and map out a plan for your internet business model. What market are you targeting, and how can you best serve that market? This is the angle you want to work from, vs the more common: how can I make the most money from this market? (Most people get it backwards and then get frustrated when that doesn't work out for them)
Whether for high school students or adults, you can monetize your expertise by teaching people with less experience or knowledge than you in that subject area. You can work with an established group like Kaplan for, say, SAT tutoring, or you could try hanging out your own shingle and making your services known either to students, parents and schools in your community. If you are targeting adults, you can create your own website or list your services with adult tutoring companies.
Don’t worry, this isn’t as sinister as it sounds. Most unis are constantly looking for volunteers to take part in studies, and usually offer money as a reward. Investigate what your uni has to offer, and check your emails to see if there’s any information about it on there. One of my mates was paid £20 for spending two hours listening to music. That’s a night out. Definitely something to look in to…
