How Can I Get Started In Real Estate Investing Without Much Money?

I am 24 years old, I graduated from college last year. I work as a contractor right now with some guys. I really want to be a real estate investor. I want to start with small rental properties, but all the money my wife and I make pretty much pays the bills and we don’t have much left over. Also, I never know how much I will make each week because work is unpredictable, so I know a conventional loan is pretty much out of the picture. Any advice anybody?
