I found this web site http://btcgoi.com/#sellbitcoin they are supposedly buying Bitcoins + %

sounds fishy, AFAIK, none is buying bitcoins for +% , if I were you, then i will avoid that site at all cost.
+1 on this. There is no reason for a website/company to buy bitcoin at above market price. If they were in need of bitcoin then they would buy them on an exchange.
