well, my dear, let me say this, it's not just money that you need, but enough women who are interested enough to do it.
The concept of a sorority is fairly new to international people besides US and canada, so I highly doubt the stereotype will follow through. What you want to do is to introduce it to your friends and see if they would like to join one. if you are still in school, talk to your student activity council to see what are the procedures.
I personally don't know anything about NPC sororities chartering a chapter overseas, but as others point out, you may want to contact a sorority after you have enough people.
Though, this is just my opinion, that you might be better off starting your own. The question is, does risk management prevent having oversea collegiate chapters and how hard the process is? I know for other sororities in order to start a chapter, your charter sisters and the HQ have to travel back and forth to regulate the process. So distance could matter...
