I can explain how to get work done for $0:
Post project, select freelancer, get work done, send payment to freelancer, mark project as complete, receive good rating,
Next - CHARGEBACK your money. Freelancer.com will do chargeback in any case, next reverse transaction and remove money from freelancer's account.

If you are a freelancer and you are still not victim of this business schema - it is your personal luck. New transaction like "Reversal of [Done milestone payment from ABC for project XYZ... " can appear at any moment.

Freelancer.com know about this business schema (please, note how politely I name "robbery") but doing nothing about it. Because Freelancer.com receive "introduction fee" from freelancer in_any_ case. Say, for $1000 project Freelancer.com receive $100 as introduction fee from freelancer. And doesn't matter Cahrgeback done or not done.
