The average length of time that someone is unemployed for in America today is eight months. In many states, unemployment benefits only last for six months. Although this has been extended through several federal programs, the best way to extend your unemployment benefits is to take on small jobs while you continue your job search. In most states, reporting the income from a part-time job can lead to an increase or an extension of your unemployment benefits. These jobs are part-time and flexible, so they won't interrupt an interview schedule and can be done around free childcare options.
Freelance Writer
There are a lot of Internet start-ups looking for content. Write articles about what you know, and sell them through one of the many clearinghouses for Internet sites. Payment is usually determined by the amount of traffic your articles generate. Expect about $5-$10 per article, paid in installments over a year.
House/Office Cleaner
A lot of people and businesses who hire professional cleaning companies are looking to save money in this economy. By not having office space or a receptionist, private housekeepers are much cheaper than professional companies. Advertise on craigslist or by dropping of business cards at local businesses. Pay is about $25 per hour.
Lawn Service
Just as with housekeeping, this is another area people are trying to cut back on. The elderly and young families often need help with bigger projects such as lawn mowing and weed removal. Pay is about $30 an hour.
Childcare
Laws vary by state, but typically you don't need a license as long as you are watching less than 3 kids for less than 30 hours a week. A lot of parents just need a safe place for their children to go after school since after-school programs are getting cut. Elementary aged kids usually just need some basic homework help and a snack. Pay is about $5 per hour, per kid.
Survey Taker/Mystery Shopper
Scams for these kinds of jobs abound on the Internet, but there are some legitimate opportunities. Avoid anything that asks for money up front (no legitimate site will do this). In general, taking surveys works best if you live in the suburbs or a rural area of the country and have (or used to have) an above-average income, as this seems to be the demographic most companies are interested in selling things to. Mystery shopping works best if you live in a city, since most national chains that hire shoppers have stores located in these areas.
Payment is not reportable on your income taxes, but most of it is in the form of free sample and gift certificates. Expect about $25 to $50 a month.
