    “This is the first time I use Freelancer, and I feel very lucky. I was excited so I posted the project. We had some misunderstanding but Jin was very patient with me. I read so many bad reviews about the site, and of course I was worried. So far, things went well. I made some designs and Jin can make it a reality. Not perfect, but he is willing to make it perfect, how I want it. I will wait for his updates. A professional and kind man you should work with!”
