There are few genuine freelancers out there, but most of them fake 'experts' they show others' work as their own but when you get the job done it'll be sub-standard quality.
I suggest you only work with a high rating freelancer (Top 1% or so).
PPH customer service is very poor, if you file a dispute they ask you to work directly with a freelancer, but still charge 10% commission from you for doing nothing.
