Neighbors are a great way to earn a little extra cash! Lots of dogs around? Ask to walk their dog(s) every day, or dogsit while they're away! Neighbors, that need some help with their yard? Ask to do some landscaping! Mow their lawn, plant some flowers, weed their yard, start a garden, water their plants, etc. Maybe you could clean their garage or wash windows? I recommend meeting in person and not just putting posters around your neighborhood. Don't forget to tell them why you want some more money. Saving for a car? College? Summer fun? Be honest!
Websites like Survey Junkie will pay you a decent chunk of change for the low-maintenance, borderline mindless task of completing surveys. Companies want to understand consumers better, and one way they do that is by compensating survey-takers. Most surveys pay between $0.50 and $1.25, and many of them take less than 5 minutes to do.
