Upwork use to be good but they take 20% and people demand you to just 2 hours of hoops before they will hire you it's horrible. What an abuse. 

Someone needs to make a reasonable platform with 3 to 4% with little waste of time maybe short test project and they like you they give you more not waste 2 hours to give you 40 Euros of work that takes you a day to finish then they want 20 fixes.
