I've done some freelance work in the past but mainly got it through a friend. I would consider this "true" contracting. I was given the requirements of the project, made an estimate, billed my hours, and got paid on a 1099. I had a deadline but worked my own hours. Obviously this is on and off and not enough to maintain a good income.
Now most "contract" work I see online (Dice, careers.stackoverflow.com, careerbuilder) or from agencies (KForce, Robert Half, etc) is not true contract work. It is on-site office based work with set hours even though they consider it contract. This is true for sysadmin and programming work.
So where does one find "real" contract work besides networking. I would consider "real" contracting work as taking a job, working your own hours (but meeting a deadline), and delivering a product. (i.e. I need you to write backend API to do X, Y, Z). Is my definition of contract work twisted?
I've looked at Odesk but it seems as you are competing against people and skilled programming work bids at $10/hr. The point of a contractor is to sacrifice job stability for higher pay and more freedom. I'm open to sysadmin or programming (PHP, Perl, Python) contracts.
