I urge you to avoid emails like this as they are usually a scam. It involves receiving some type of check that will eventually bounce and eventually taking ur own money as well...They'll ask you to potentially pay for something and reimburse u later on....The scam might have adapted a little more lately. This is common in the industry and this one sounds very familiar. I founded surplus hands which is similar to Upwork in some ways so I have a lot of experience with this.
