It looks like wordpress has some nice free one page templates... but 1) it might be overkill for your need 2) I just discovered wordpress so... I may have false hopes 3) in any case: either you buy a template & customize, hire a designer, or get your hands dirty

Depending on what you need, http://html5up.net/ has some free templates. I'd also be willing to build you a custom page.

Curious: Where are you buying templates?
