NO! We really have not looked real hard at them, but we know that they usually do a bid system and they charge for it.
One we heard of charges you in the $20.00 area to make your need more visible. They take 10% of what the Freelancer gets. They try to charge the Freelancer for tests to make them look better. They do not let client and Freelancer know very much until a SALE is made.
Our Freelancer members are welcome to contact you, and can put URLs up so you can see work they did and talk to you by email, phone, skype, or any other means to make sure you both know what you are doing.
You are welcome to contact them as well. Any way that is comfortable.
All we can ever make is about 5.00 from how ads are done. That is all we ask and that is voluntary.
