I mean how to make quick and easy money from Singaporeans. It is a piece of cake. Just sign up with a foreign party, form a company, create a beautiful catalogue of prime housing in a foreign shore, the best is Bintan and Batam. Then sell them to Singaporeans.
In the process of selling, build a few units as show houses to lure more Singaporeans in and put in more deposits. Then when enough is collected, just fold up and disappear, with the money of course.
