Develop a good relationship with your recruiter at a personal level, whatever company it may be (2-3 recruiters for different companies). Even if you have to fly across the U.S. and pay for $400 round trip ticket, and pay fora $200 lunch/dinner and treat the recruiter. Get to know them, they will tell you what contracts are starting/finishing....boom...you paid around a $600 investment for a $4000-6000 return per week for a 1-3 month contract (you can do the math).
Do this, and you'll always keep it going as long as you want.
