Hi. I have a client that lives on another side of the planet, in Argentina. He pays for my work via Paypal but it's expensive for me because of each paypal transaction costs and because of converting currencies from Argentinian pesos to USD to EURO. I just lose money  . My client is not into bitcoins. How can i guide him to make him buy Bitcoins with Argentinian pesos (paying with credit card), in a way that he does it quickly and with no complications?
