I'm having the same, now I'm earning by renting Upwork accounts. Your offer is much better than mine.
I only recieved $150 per month, and PC's are provided by my users.
Now I'm a small time broker providing a verified Upwork account to my renters.
All I can say is this is Legit since I can see all the works and their account transactions, and I know all the passwords
of all the accounts I provided to them. So it's safe, I also able to build to good relationship with with Renters.
Anyway please be careful, still there are some people who are scammers and pretend to be legit like them.
