Correct me if I'm wrong but I read the Whitepaper a little and I have some question about this.There are other "Freelancing network on blockchain" projects out there but none of them provides a service with no fees like you do but according to your Whitepaper the customer will have to transfer their fiat money to you which they will pay some fee and the person who accepted the job will have to pay another fee to withdraw.You can't say there are no fees and since you didn't told us how much is the "small fee" it might be even more then the other services.

Second problem that you didn't clear out is a general problem about freelance services.Will you have a quality control team? A contractor might deliver a bad quality work and they might have demand money from the customer.As an escrow like service what are you going to do? Will you give money to the contractor because he spent his time or the customer will get his money back and also will have possession of the work that has been done.

Thank you for your time if you answer my questions.
