Sadly as per the advise above you need a huge amounts of money, tyou can start of with just 100 a month below. This would give you a kickstart
You may want to look at fundsupermart for unit trust.
You can look at bond funds and global equity
You may also consider getting a saver plans from manulife,
ntuc income,....
Basically, you put in few hundred dollars a month and get back a small return
eg principal + 3% something like that
