Is BrokerOfficial Good or Bad?

Hi
I have a question.. honestly I know nothing about brokers and trades or anything like that.. But my family member has been talking to this Broker/Trader based in London.. S

he’s been telling him that she can turn $5000 into $50,000 in 90 days. sent him via email all kinds of “official” looking paperwork to prove she legitimate.
Im super skeptical, it sounds a little fishy to me. But he’s really considering it. How can i prove it. The name of the person is “suppose” to be Victoria Sharp..

I cant find anyone with that name on the internet
