I have dedicated server and WHM and WHMCS installed. I want

Hi,
I have dedicated server and WHM and WHMCS installed. I want to do web hosting to 2 different market. One is globally and one is locally to my own country only. The pricing will be different. Simply because my country hosting is a little bit expensive so i can get higher margain. but i dont want to lose customer globally because of the slightly higher priced hosting. currently i install WHM & WHMCS to abc.com. how can abc.com check if the customer is from my country, it will show just my currency and my higher priced hosting package while if its from let say USA, europe, it will show a general pricing and USD currency. and what plugins do i need? the simple solution i can think of is in WHMCS offer two currency which is USD and my local currency. but if they see there is pricing difference, they might even opt for usd instead of local currency since they can change it via the web. thanks.
