I have accidentally paid you USD20 a few days ago - without any work done. I was very upset at first, then I thought it might be a good idea if I get you to do one SEO job for me. Let me know if you are interested.
After all, you have taken my money from me with no work done. You may as well do one job for me. and if you were to do well, I will give you more SEO jobs.
Let me know if you are interested.
