One of my companies is incorporated in Singapore. IIRC, it cost us between US$ 5-6,000 to register the company. Yearly maintenance cost is US$ 2,000+ (that includes a local business address, the services of a local director, bookkeeping staff etc.).
We're using services of a firm called Rikvin assoc. They're kind of expensive. If you're physically present in SG, you may find cheaper alternatives.
Are you affiliated with Rikvin? You can register a company in Singapore at $15 one time charge. All these company maintainers are scams, offering EP, tax filing and what not. Singapore is so very business friendly and have e-governance. No need to hire such firms there.
