This will be a exploding feature here on steemit for the artists like us. I am really searching for these types of platforms to sell my services. I currently sell my services on fiverr but there fees are ridiculously high at 20% and after that paypal charges 8% so overall I lose my 28% money without no reason. If any platform is set up on steem blockchain and we can sell our services there, we will really save a lot. I wish this feature will definitely take shape in the future.
