Who doesn't like to shop? Online, at the mall and even in airport gift shops, shopping is just downright thrilling wherever the location and whatever the purchase. But whoever thought shopping could be considered a hobby, especially because if you're good at it, it requires inordinately large amounts of cash? If you've maxed out one too many credit cards, maybe it's time to start spending someone else's money. Personal shopping is a great source for extra cash, because clients pay you to do their shopping. Duties could include finding a client that perfect dress for a fancy gala, or simply picking up medicine from the pharmacy or groceries from the supermarket. Print up business cards to hand out every time someone compliments your outfit, or offer your services to busy moms or senior citizens in your neighborhood. A part-time or beginner personal shopper might charge anywhere from $15 to $20 an hour, or 10 to 15 percent of the total purchase [source: PayScale.com]. However you bill your customers, you're certain to make enough to indulge in a few purchases of your own.
