Don't turn him down. Merely quote him the price you need to either outsource the content so that it is written extremely well, or the time it'll take you do do the research to write the content extremely well. Don't shortchange yourself on this - make some money. But don't just say no. Offer him a price, and let him make the choice to tell you no.
However, one other thing. You said:
All that is important in the website is the company name and contact info that would appear on the landing page.
No. All that is important is company name, contact info, and a form that lets them request a call back. Missing that form is going to let 90% of his traffic dribble away to the competitors. And I'd put the contact form as more important than their contact information, particularly for a service oriented business.
And don't neglect LifeinAsia's points either. They're all important. And by important, I mean, they make money. That's important right? :).
The three posts preceding mine are pretty exactly what you should be reviewing and considering.
