This client mainly deals with Amazon. He consulted me about the full set of Amazon services in early April. He had a good impression of me after a brief communication. Later, I added the client on WeChat and told him that we specialize in handling US business. I asked the client when he would consider processing the matter. He said he would discuss it with his friends and it would take some time. However, he sent me a WeChat message after a while and asked me to send the agreement. Then I paid on Monday.
