Good at scheduling and organizing? Consider being an assistant. Earn $45 to $50 a day executing other people's random tasks either in your own town (such as getting groceries for another family while you're getting some for yours, picking up someone's dry cleaning while you pick up yours, etc.) or assist virtually. The site taskrabbit.com, for example, has a long list of "virtual assistance" gigs you can do via your laptop, ranging from data entry to online research. The best part: You can work from anywhere. The more technical your skills, the more you can charge.
Strong knowledge of a particular subject matter? Try online tutoring. At tutor.com qualified tutors work with students via video conferencing and online chats, earning an average $10 to $14 per hour. Math and science tutors earn the most.
How to get started: You don't have to be a certified teacher to qualify, but you do need to have a college degree or be in the midst of earning one. The process isn't just sign-up-and-start, though--there's an online application, followed by an exam, a tryout session, a background check, and another exam. The good news: You only have to test in the area you'll be teaching, from math and science to writing and job-interview prep.
Love pets and have room in your house or backyard? Make money by pet sitting and pet boarding, that can bring in an average $20 per pet, per day. Parents can even involve their kids with this stay-at-home business.
How to get started: Do an online search for pet boarding sites that connect pet owners and pet sitters. For example, sleepoverrover.com, is a Phoenix-based site that handles all advertising, reservations, and payments between pet owners and boarders. (Another option: Partner with a local vet or pet store and ask them to refer people to you.)
Own an up-to-date computer and a landline phone? Turn your home into a call center for reservations or customer service. How to Get started? Many companies hire at-home customer service reps, such as Hilton Hotels and 1-800-Flowers. Pay is usually $8-$10 an hour and you want to set aside at least 15 to 20 hours a week for this, but many times, call centers are 24 hours, so the hours can be flexible.
