Elance / Simply horrible
Elance is a joke if you are looking to provide quality work (and get anything close to a fair wage). For buyers it's even worse. The whole site is chalk full of low-quality providers with glowing resumes and feedback. The thing is the providers make multiple accounts and "trade" projects within the accounts for that very feedback.
Elance turns a blind eye so they can collect their service fees.
Their escrow isn't a real escrow system, the website itself has errors all the time and if you are looking for any type of customer service or support you get a phone answering machine and an email support service that never returns emails.
Elance is by far the worst freelancing site I have ever had the misfortune of working with.
If you ever think of checking it out be sure and READ their 800 page terms of service statement. They are not responsible for ANYTHING. They can come back and take money you made months ago if they want (and they have citing problems and fraud)...even though their system is supposed to prevent these things.
Elance is a joke and a horrible affront to decent business practices.
