How does one go about adopting in Singapore? What's the process, fees etc?

According to the article below, it can cost about $28 000 to adopt a child via adoption agencies in Singapore. Out of the said amount, about $10 000 - $16 000 will go to "red packets" for the baby's mother (who usually hail from poor backgrounds), about $1000 for the mother's pre/post-natal expenses etc and a substantial amount goes to administrative matters like checks on the documents needed for adoption e.g child's identification papers, notarised consent from the birth parents giving the child up for adoption, and a declaration by prospective adopters that the child is not obtained through illegal means. http://yourhealth.asiaone.com/content/adoption-singapore-it-may-cost-28000-baby/page/0/0
