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.
Find a profitable niche. Starting with your interests, write down as many niche ideas as you can. Think about topics people might search online. Ideas include passions (like surfing or body building), fears (like spiders or speaking in front of crowds) and problems (like getting out of debt). Do keyword research to see it others are interested in the topic. Find out if a domain name is available that matches the keyword 100 percent. 
Fiverr: Israeli-based Fivver was started in 2010 by Shal Wininger and Micha Kaufam. It's a great resource for selling just about any service online.

the problem with “CashCrate” is that the amount of money that u get out of it is VERY slim.. and even to get that VERY slim portion of money you have to complete a lot of surveys and to cash-in on the money you earned u must make over $20, trust me. i tried it, it took me over 6-12 months to get the cash.. i used the site like if my life depended on it. it was very hard.
Food. The second word in “Bed and Breakfast” is just as important as the first. Some B&Bs have tried to serve their guests muffins, juice, and coffee in the mornings, but the most successful hosts understand that the breakfast they serve will make a lasting impression on their guests. You can get creative and serve the type of breakfast traditional for the area that you’re in. For instance, if your home is located in the South, then eggs, grits, and biscuits may go over well, while Southwest guests may appreciate a traditional Tex-Mex meal. Whatever you decide, make it memorable and make sure that your guests feel welcome and appreciated. Make it memorable, and they’ll spread the word for you.

Love dogs, but not ready to get one of your own? Get your fix by taking care of other people’s pooches — and get paid for it. If your home isn’t dog-friendly, consider becoming a dog walker.

Dog sitters on Rover.com, the go-to site for pet-sitting, generally command $25 to $35 a night, according to the company.
