We deal with a couple of companies in Asia and if you send one email you get a flurry of these type of emails from opposition companies or companies that just dont exist landing on you emails.What a scam!
The internet and email is full of them, don't fall for it. If the English is that bad they are probably in Nigeria or some other place that is known for scam artists. An offer for work on the phone by email? Lots of money but you need to spend $10,000 first? Guarantees? Corona-virus not even spelled correctly? Did you google the company? I hope you did not reply to them or open any links. This not a genuine offer of anything but to get some money from you. They target older people, I am 77 and I am the #1 skeptic of anything, I don't believe anything unless I can verify it for myself through an unconnected source. So far this has served me well.
Hazards of dealing overseas
I think they are all hacking each other just to get your business or like you said scams.
Its like a flock of seagulls following you down the beach when you eating fries.
But this last one was just amateursville..
