This is the internet. NEVER trust anyone that willing to offer to do your work, and all you need to do is pay them for the service. So, is it a scam? Is it any better than the constant e-mail I get from someone in some third world country, offering me millions of dollars, if I only send them my financial information so they can transmit the money? This is hard to know. Are there differing degrees of scams and spammers?
Perhaps at best, this is a person who is so desperate for money, they are willing to offer the service of doing any job for you, without knowing even what you need to do. My question would be how good are they really, if they cannot find an honest job? Is it worth the risk?
There is always someone willing to take you for a ride, if you are only foolish enough to take them up on the offer. What did PT Barnum say, about a sucker being born every minute?
Instead, do your own work. Create something from your own efforts, something that you can be proud to say was entirely yours.
