Does it snow where you live. Theres lots of people I know who plow snow for a living (like use a pickup truck with a plow) and they take 5 minutes at the most to plow one driveway, and make 50-100$ each, and can plow up to 30 driveways a night.

-You can teach i.e. basic computers, setup emails and Facebook accounts, Word or Excel etc.

-Find a distributor of DVD movies, get them for $1 a piece. Find a partner, setup shop at a local flea market and sell them at $5 a pop. .
-Learm how to play poker. Not just how to, how to run a game. Learn how to collect a rake from a pot. Learn how to deal cards. Find underground clubs around you and play a bit until you're trusted and offer up that you can deal for them if they need someone (maybe $200 a night in your pocket). If that fails, get your own club up and running. Dealers are free,

The latter two points are more in the high risk margin of ideas. Every risk has its pros and cons. Consider them before you put anything or everything on the line. For about twenty bucks you can buy paint rollers and brushes and borrow someones ladder if necessary. Put a free add on Craigslist for affordable painting, or deck staining,gutter cleaning, leaf raking, household chores, trash removal, pool cleaning,(you fill in the blank) in nearly any of these the homeowner will pay cash.
•Child Care Jobs
The best way to get your foot in the babysitting business is to care for children you know. You can then use these references when you branch out find new clients. Many parents feel uncomfortable with the idea of leaving infants or babies with inexperienced baby sitters, so you should not expect to care for little ones when you get your first job. Start with children ranging in age from 6 to 10, and, as you gain experience, you can care for younger children or children with special needs. People with baby sitting experience can also advance to nanny jobs or au pair positions. Most jobs pay cash immediately, though long term or regular positions may develop scheduled payments based on the situation.
•Delivery Driver Jobs
The quintessential all-or-almost-all cash jobs can be found in areas like pizza delivery and courier jobs. These jobs are usually predominantly tip-based, which while still counted as taxable income (just like all other forms of income), they tend to be primarily in cash. Drivers for these types of jobs can routinely make a few hundred dollars per week just in cash tips, and typically earn a small base hourly pay for their services as well.
•Lawn or Garden Care Jobs
Many people either do not have time or the ability to care for their lawns. A popular cash job is to mow lawns, trim trees, cart debris away or rake leaves. If you live in a snowy area during the winter, you can also earn cash by taking snow shoveling jobs. The best way to find these positions is to post an ad for your services at the local senior center or recreation area. You can also post your name and phone number on public bulletin board space at churches, public transportation centers or grocery stores. As you gain experience in lawn care, you may be able to find a position as a gardener or landscaper.
•House-sitting or Pet-Sitting Cash Jobs
Many people need occasional help with their pets or home while they travel for business or go on vacation. Holiday seasons and the summer months are booming times for this cash business. One of the best ways to find clients is to ask for referrals from clients you already have. If you baby sit or do yard work already, mention that you would be happy to house sit or care for animals when clients go out of town overnight. Also, pet walking is a popular cash job in some areas. Some people hire dog walkers to let their animals outside during the day while the owners work. Post your information at places like veterinary clinics, animal shelters or pet supply stores to find new clients.
•Cleaning Jobs
Some people do not have the time or energy to clean their own home. You can turn this need into a lucrative cash job. Again, post advertisements with your information at community centers to find clients. Some people who clean to earn cash charge by the hour, while others charge by the square footage of a home or number of rooms.
•Companion Jobs
As the population ages, more and more older people are living with their adult children. Others are living alone but need assistance. With the proper preparation, you can turn this into a cash job. Many people are looking for companions to their elderly parents. People who live with and care for their elderly parents or family members may need to hire a companion when they leave to shop or go to work. Other people may hire a companion to help elderly relatives with house hold tasks like opening a jar or medicine bottle. This cash job may involve light cleaning and cooking as you help elderly people with
