There are numerous ways to earn extra income, including getting a part-time job, starting a business, offering one's services, such as dog walking or babysitting, or pawning valuable items. Some tasks allow individuals to earn quick cash, while others require a little time before making money is possible.
Individuals looking to earn quick cash can sell items they no longer need at a yard sale, or look in their closets for items that still have price tags and return them to the store. Others can scour their furniture, cars and piggy banks at home for coins and convert them into bills at their local banking institution. Asking friends or neighbors if they need assistance walking their dogs or house sitting while they are out of town are additional ways to earn quick cash.
Applying for a part-time job and waiting to be hired may take a little longer; however, jobs that pay cash daily -- such as waiting tables or bartending -- allow individuals to bring home money almost immediately after they start working. Starting a business may take even longer to get started; but entrepreneurship may be a worthwhile endeavor with a good product or service and adequate marketing and advertising.
Additional ways to earn extra income include selling scrap metal or items on websites, such as eBay or Craigslist, selling hair or blood plasma, participating in clinical trials or sperm donation.
