Searching for that additional S$10 per month

Dear Reader,

I am looking for that additional S$10 per month passive income to hit my $200 per month goal for year 2008.

With current liquid cash of slightly over $20000, that leaves me with a roughly $1500 to $2000 (after setting aside 6 months of emergency funds) to invest to get that additional S$10 per month.

Any advice?
