Send relevant writing samples. If someone asks for a marketing writing sample, send them marketing writing samples. Don’t send a finance article. Or a fitness one. It’s hard for a hiring manager to know how well you understand the niche’s industry if they can’t see a relevant writing sample. Apply to opportunities suited to your skill set and experience. Also, if your pitch doesn’t have a list of links to writing samples, it’s going to get ignored.
People are always looking to have their cars washed and detailed. You could be a mobile car washer and detailer with a permanent location. Reach out to people you know or make some flyers and put it in your neighbors' mailboxes. If you want to get serious about it, prop up a one-page website or give out business cards. You can make money quickly doing this.
Set up a roadside stand. Depending on where you live, you could profit handsomely by setting up a roadside stand. If you live near a resort area, for example, you could buy cases of bottled water, put them on ice, and sell them to passers by for twice what you paid. Selling fruit and produce you grow yourself is also a smart idea in highly-traveled areas.
Monetize a hobby. While some hobbies actually cost money, others can be transformed into a profitable business venture. Ultimately, it depends on what your hobby is and how talented you are. You could turn your love of photography, for example, into a part-time gig taking family portraits and wedding photos or selling prints on Etsy or at arts fairs.
Use a credit card’s cash advance feature. Some credit cards will allow you to withdraw a certain amount of cash by using it at an ATM. This can help you come up with cash in a hurry. However, the interest rates on cash advances are usually much higher than the credit card’s usual interest rate, meaning that you will eventually have to pay more.
Turn your photographs into cash via sites like Fine Art America, which lets you upload your images to sell as prints, t-shirts, phone cases and more. Other marketplaces for photographers include SmugMug, 500px and PhotoShelter. Some sites require a subscription but may provide features ranging from cloud storage to password-protected galleries and a customized website.
If you have more internet bandwidth than you know what to do with offer to share with your neighbor for a small fee. Label your SSID (the name of your WiFi network) something like “Visit apartment 207 for internet.” If you have fiber optic internet at 50 to 100 mbps you could possibly rent up to 15 people easily and still have lots of bandwidth. This is a great way to earn money fast.
