It was an unexpected experience. Since this is my first freelance service I never thought I will have this much tension. When Buyer sent me the messages I was happy and anxious at the same time. Well now I have completed my first order I feel relaxed. The job I provided has given me 66$ though now I think it was a bit less. Well, next time I will be better at negotiations.
I am very thankful to Fiverr for inspiring me to start my freelance career.
