Dear, Sir
I am glad to bid you.
I read your job deeply and I think I am very qualified for you.
Now I have no reviews on Freelancer.com.
But in fact I have talent.
I can show you my talent just now.
I don't want any upfront.
Only when I finish the job perfectly, I will talk with you about the payment.
I sincerely hope to work with you.
Kind regards.
Hans.
