Most people do not have a lot of money when they are trying to start a business so why not try your hand at the landscaping/maintenance business? While it may seem difficult, you can literally start with just a lawn mower and a tank of gas. Head out to your neighborhood and start knocking on doors to get some clients. You can even offer to do the first cut free to try and gain their business!
This is a great idea because it can be a full-time business no matter where you live. Once the weather starts to get a little chilly people will need to use you for raking their leaves. After the weather turns really frigid you can go around to the same people and offer to shovel their driveways. At first you may work very hard with primitive tools, like a shovel and rake, but after a year of building clients you will probably be able to upgrade all your equipment to start making some real money!
