Can this be real?
Yup it's for real. Just wire him the money and the job is yours. I'm from Eritrea and when he contacted me everyone was like, no! Don't do it it's a scam and I was like f tat, I'm doing it. Now i live haply in Poland and I even got me a nice polish wife! Go for it.
In retrospect I think it's hilarious that a Polak is trying to scam the Nigerian prince.
