How long does it take to style a page like this in Drupal?

It depends on how good your developer is! You would start with a Drupal theme which is the most similar to this and make changes. It's a total GUESS to say it might take a few days to do this, or possibly a few weeks, depending on the amount of tweaking that needs to be done.

I would have to agree with nanharbison that you should be able to find a Drupal theme with this basic layout.

After that, you have to put your own content into the template.

Also, you have six menu items (pages) on this site. How many you need, other than the Home page, will also have an influence on the time required to set it up.

Finally, this may be more easily done using WordPress.

I appreciate the input. We're already working with a developer, and trying to figure out a proper time frame. For the sake of this question, I'm not thinking about the entire website...I'm thinking how long would it take a competent developer to style just this one page?

An hour, a day, three days...?

Thanks!

It will also depend what you expect of the site. If you want a responsive design, it will take a few more days. It also requires more testing

"I would say 3 days is more reasonable."

Wow. Three days just to get this one page laid out and populated? (Again, not the whole site...just that one page)

@rightmirem - I have been doing web development for 13 years and I can tell you without a doubt that web programming and styling is WAY more time consuming that the average man on the street could understand.

If the developer is building everything from scratch on the back end, easily three days of dedicated time. If the developer isn't completely dedicated to your project(most outside consultants juggle multiple clients and projects) then expect much longer.
