  • image of 1EasyEcommerce-New Jersey Project for Dimitris K. -- 9 $180.00 USD

    “Perfect as always, thanks for your help”

    “I do not recommend this freelancer because he is not very correct. He took advantage of an emergency situation to intervene without us having agreed to the amount of his work and without having started the hiring procedure. Usually, the other freelancers, quickly study the problem and confirm the price before intervening. Then we hire. We told him that his hourly rate was $ 1200 / hour and not $ 50 / hour as shown on his profile. He did not want to reassess his offer. If you talk to him, ask him not to intervene until you have agreed to his offer.”
