How to tell if a company is legitimate?

They are both likely fake... The websites are written in poor english, Maxwell doesn't even define the area of business (merely saying business) and they don't appear on "Companies House" website. No job will ask you to cough up money in order to pay someone through your bank account. It is nonsense. Companies have their own bank accounts, if they need you to pay something out of your own account rather than from their accounts then I would be hugely suspicious. Something does not add up if you come to them to get money and they ask you to distribute money for them from you.
