I lost nearly $1,000, after a projected estimated at 4 weeks, took SIX MONTHS, and still wasn't nearly complete. I disputed with guru.com who had my money in escrow, and they still awarded the money to the developer even though the site wasn't functional. I provided 10 examples of where the developer failed and it still wasn't enough for them. Avoid guru.com, and if you do use them, never pay anything in advance, and don't put any money in escrow.
I disputed a second project with my credit card and Amex saved me from losing another $500 on that.
Guru.com is useless.
Monetary Loss: $1.
